- Only read-only commands are executed automatically
|
## eBPF Monitoring Capabilities
|
||||||
- Commands that modify the system (rm, mv, dd, redirection) are blocked by validation
|
|
||||||
- The resolution plan is provided for manual execution by the operator
|
The agent includes advanced eBPF (Extended Berkeley Packet Filter) monitoring for deep system investigation:
|
||||||
- All commands have execution timeouts to prevent hanging
|
|
||||||
|
- **System Call Tracing**: Monitor process behavior through syscall analysis
|
||||||
|
- **Network Activity**: Track network connections, data flow, and protocol usage
|
||||||
|
- **Process Monitoring**: Real-time process creation, execution, and lifecycle tracking
|
||||||
|
- **File System Events**: Monitor file access, creation, deletion, and permission changes
|
||||||
|
- **Performance Analysis**: CPU, memory, and I/O performance profiling
|
||||||
|
- **Security Events**: Detect privilege escalation and suspicious activities
|
||||||
|
|
||||||
|
The AI automatically requests appropriate eBPF monitoring based on the issue type, providing unprecedented visibility into system behavior during problem diagnosis.

## Safety
|
||||||
|
|
||||||
|
- All commands are validated before execution to prevent dangerous operations
|
||||||
|
- Read-only diagnostic commands are prioritized
|
||||||
|
- No commands that modify system state (rm, mv, etc.) are executed
|
||||||
|
- Commands have timeouts to prevent hanging
|
||||||
|
- Secure execution environment with proper error handling
|
||||||
|
- eBPF monitoring is read-only and time-limited for safety

# eBPF Integration Complete ✅
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
Successfully added comprehensive eBPF capabilities to the Linux diagnostic agent using the **Cilium eBPF Go library** (`github.com/cilium/ebpf`). The implementation provides dynamic eBPF program compilation and execution with AI-driven tracepoint and kprobe selection.
|
||||||
|
|
||||||
|
## Implementation Details
|
||||||
|
|
||||||
|
### Architecture
|
||||||
|
- **Interface-based Design**: `EBPFManagerInterface` for extensible eBPF management
|
||||||
|
- **Practical Approach**: Uses `bpftrace` for program execution with Cilium library integration
|
||||||
|
- **AI Integration**: eBPF-enhanced diagnostics with remote API capability
|
||||||
|
|
||||||
|
### Key Files
|
||||||
|
```
|
||||||
|
ebpf_simple_manager.go - Core eBPF manager using bpftrace
|
||||||
|
ebpf_integration_modern.go - AI integration for eBPF diagnostics
|
||||||
|
ebpf_interface.go - Interface definitions (minimal)
|
||||||
|
ebpf_helper.sh - eBPF capability detection and installation
|
||||||
|
agent.go - Updated with eBPF manager integration
|
||||||
|
main.go - Enhanced with DiagnoseWithEBPF method
|
||||||
|
```
|
||||||
|
|
||||||
|
### Dependencies Added
|
||||||
|
```go
|
||||||
|
github.com/cilium/ebpf v0.19.0 // Professional eBPF library
|
||||||
|
```
|
||||||
|
|
||||||
|
## Capabilities
|
||||||
|
|
||||||
|
### eBPF Program Types Supported
|
||||||
|
- **Tracepoints**: `tracepoint:syscalls/sys_enter_*`, `tracepoint:sched/*`
|
||||||
|
- **Kprobes**: `kprobe:tcp_connect`, `kprobe:vfs_read`, `kprobe:do_fork`
|
||||||
|
- **Kretprobes**: `kretprobe:tcp_sendmsg`, return value monitoring
|
||||||
|
|
||||||
|
### Dynamic Program Categories
|
||||||
|
```
|
||||||
|
NETWORK: Connection monitoring, packet tracing, socket events
|
||||||
|
PROCESS: Process lifecycle, scheduling, execution monitoring
|
||||||
|
FILE: File I/O operations, permission checks, disk access
|
||||||
|
PERFORMANCE: System call frequency, CPU scheduling, resource usage
|
||||||
|
```
|
||||||
|
|
||||||
|
### AI-Driven Selection
|
||||||
|
The agent automatically selects appropriate eBPF programs based on:
|
||||||
|
- Issue type classification (network, process, file, performance)
|
||||||
|
- Specific symptoms mentioned in the problem description
|
||||||
|
- System capabilities and available eBPF tools
|
||||||
|
|
||||||
|
## Usage Examples
|
||||||
|
|
||||||
|
### Basic Usage
|
||||||
|
```bash
|
||||||
|
# Build the eBPF-enhanced agent
|
||||||
|
go build -o nannyagent-ebpf .
|
||||||
|
|
||||||
|
# Test eBPF capabilities
|
||||||
|
./nannyagent-ebpf test-ebpf
|
||||||
|
|
||||||
|
# Run with full eBPF access (requires root)
|
||||||
|
sudo ./nannyagent-ebpf
|
||||||
|
```
|
||||||
|
|
||||||
|
### Example Diagnostic Issues
|
||||||
|
```bash
|
||||||
|
# Network issues - triggers TCP connection monitoring
|
||||||
|
"Network connection timeouts to external services"
|
||||||
|
|
||||||
|
# Process issues - triggers process execution tracing
|
||||||
|
"Application process hanging or not responding"
|
||||||
|
|
||||||
|
# File issues - triggers file I/O monitoring
|
||||||
|
"File permission errors and access denied"
|
||||||
|
|
||||||
|
# Performance issues - triggers syscall frequency analysis
|
||||||
|
"High CPU usage and slow system performance"
|
||||||
|
```
|
||||||

The Linux Diagnostic Agent now includes comprehensive eBPF (Extended Berkeley Packet Filter) capabilities for advanced system monitoring and investigation during diagnostic sessions.
|
||||||
|
|
||||||
|
## eBPF Capabilities
|
||||||
|
|
||||||
|
### Available Monitoring Types
|

|
||||||
|
2. **Network Activity Tracing** (`network_trace`)
|
||||||
|
- Tracks TCP/UDP send/receive operations
|
||||||
|
- Monitors network connections and data flow
|
||||||
|
- Identifies network-related bottlenecks
|
||||||
|
|
||||||
|
3. **Process Monitoring** (`process_trace`)

## How eBPF Integration Works
|
||||||
|
|
||||||
|
### AI-Driven eBPF Selection
|
||||||
|
|
||||||
|
The AI agent can automatically request eBPF monitoring by including specific fields in its diagnostic response:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"response_type": "diagnostic",
|
||||||
|
"reasoning": "Need to trace network activity to diagnose connection timeout issues",
|
||||||
|
"commands": [
|
||||||
|
{"id": "basic_net", "command": "ss -tulpn", "description": "Current network connections"},
|
||||||
|
{"id": "net_config", "command": "ip route show", "description": "Network configuration"}
|
||||||
|
],
|
||||||
|
"ebpf_capabilities": ["network_trace", "syscall_trace"],
|
||||||
|
"ebpf_duration_seconds": 15,
|
||||||
|
"ebpf_filters": {
|
||||||
|
"comm": "nginx",
|
||||||
|
"path": "/etc"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### eBPF Trace Execution
|
||||||
|
|
||||||
|
1. eBPF traces run in parallel with regular diagnostic commands
|
||||||
|
2. Multiple eBPF capabilities can be activated simultaneously
|
||||||
|
3. Traces collect structured JSON events in real-time
|
||||||
|
4. Results are automatically parsed and included in the diagnostic data
|
||||||
|
|
||||||
|
### Event Data Structure
|
||||||
|
|
||||||
|
eBPF events follow a consistent structure:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"timestamp": 1634567890000000000,
|
||||||
|
"event_type": "syscall_enter",
|
||||||
|
"process_id": 1234,
|
||||||
|
"process_name": "nginx",
|
||||||
|
"user_id": 1000,
|
||||||
|
"data": {
|
||||||
|
"syscall": "openat",
|
||||||
|
"filename": "/etc/nginx/nginx.conf"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Installation and Setup
|
||||||
|
|
||||||
|
### Prerequisites
|
||||||
|
|
||||||
|
The agent automatically detects available eBPF tools and capabilities. For full functionality, install:
|
||||||
|
|
||||||
|
**Ubuntu/Debian:**
|
||||||
|
```bash
|
||||||
|
sudo apt update
|
||||||
|
sudo apt install bpftrace linux-tools-generic linux-tools-$(uname -r)
|
||||||
|
sudo apt install bcc-tools python3-bcc # Optional, for additional tools
|
||||||
|
```
|
||||||
|
|
||||||
|
**RHEL/CentOS/Fedora:**
|
||||||
|
```bash
|
||||||
|
sudo dnf install bpftrace perf bcc-tools python3-bcc
|
||||||
|
```
|
||||||
|
|
||||||
|
**openSUSE:**
|
||||||
|
```bash
|
||||||
|
sudo zypper install bpftrace perf
|
||||||
|
```
|
||||||
|
|
||||||
|
### Automated Setup
|
||||||
|
|
||||||
|
Use the included helper script:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Check current eBPF capabilities
|
||||||
|
./ebpf_helper.sh check
|
||||||
|
|
||||||
|
# Install eBPF tools (requires root)
|
||||||
|
sudo ./ebpf_helper.sh install
|
||||||
|
|
||||||
|
# Create monitoring scripts
|
||||||
|
./ebpf_helper.sh setup
|
||||||
|
|
||||||
|
# Test eBPF functionality
|
||||||
|
sudo ./ebpf_helper.sh test
|
||||||
|
```
|
||||||
|
|
||||||
|
## Usage Examples
|
||||||
|
|
||||||
|
### Network Issue Diagnosis
|
||||||
|
|
||||||
|
When describing network problems, the AI may automatically request network tracing:
|
||||||
|
|
||||||
|
```
|
||||||
|
User: "Web server is experiencing intermittent connection timeouts"
|
||||||
|
|
||||||
|
AI Response: Includes network_trace and syscall_trace capabilities
|
||||||
|
eBPF Output: Real-time network send/receive events, connection attempts, and related system calls
|
||||||
|
```
|
||||||
|
|
||||||
|
### Performance Issue Investigation
|
||||||
|
|
||||||
|
For performance problems, the AI can request comprehensive monitoring:
|
||||||
|
|
||||||
|
```
|
||||||
|
User: "System is running slowly, high CPU usage"
|
||||||
|
|
||||||
|
AI Response: Includes process_trace, performance, and syscall_trace
|
||||||
|
eBPF Output: Process execution patterns, performance metrics, and system call analysis
|
||||||
|
```
|
||||||
|
|
||||||
|
### Security Incident Analysis
|
||||||
|
|
||||||
|
For security concerns, specialized monitoring is available:
|
||||||
|
|
||||||
|
```
|
||||||
|
User: "Suspicious activity detected, possible privilege escalation"
|
||||||
|
|
||||||
|
AI Response: Includes security_event, process_trace, and file_trace
|
||||||
|
eBPF Output: Security-relevant events, process behavior, and file access patterns
|
||||||
|
```
|
||||||
|
|
||||||
|
## Filtering Options
|
||||||
|
|
||||||
|
eBPF traces can be filtered for focused monitoring:
|
||||||
|
|
||||||
|
- **Process ID**: `{"pid": "1234"}` - Monitor specific process
|
||||||
|
- **Process Name**: `{"comm": "nginx"}` - Monitor processes by name
|
||||||
|
- **File Path**: `{"path": "/etc"}` - Monitor specific path (file tracing)
|
||||||
|
|
||||||
|
## Integration with Existing Workflow
|
||||||
|
|
||||||
|
eBPF monitoring integrates seamlessly with the existing diagnostic workflow:
|
||||||
|
|
||||||
|
1. **Automatic Detection**: Agent detects available eBPF capabilities at startup
|
||||||
|
2. **AI Decision Making**: AI decides when eBPF monitoring would be helpful
|
||||||
|
3. **Parallel Execution**: eBPF traces run alongside regular diagnostic commands
|
||||||
|
4. **Structured Results**: eBPF data is included in command results for AI analysis
|
||||||
|
5. **Contextual Analysis**: AI correlates eBPF events with other diagnostic data
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### Common Issues
|
||||||
|
|
||||||
|
**Permission Errors:**
|
||||||
|
- Most eBPF operations require root privileges
|
||||||
|
- Run the agent with `sudo` for full eBPF functionality
|
||||||
|
|
||||||
|
**Tool Not Available:**
|
||||||
|
- Use `./ebpf_helper.sh check` to verify available tools
|
||||||
|
- Install missing tools with `./ebpf_helper.sh install`
|
||||||
|
|
||||||
|
**Kernel Compatibility:**
|
||||||
|
- eBPF requires Linux kernel 4.4+ (5.0+ recommended)
|
||||||
|
- Some features may require newer kernel versions
|
||||||
|
|
||||||
|
**Debugging eBPF Issues:**
|
||||||
|
```bash
|
||||||
|
# Check kernel eBPF support
|
||||||
|
sudo ./ebpf_helper.sh check
|
||||||
|
|
||||||
|
# Test basic eBPF functionality
|
||||||
|
sudo bpftrace -e 'BEGIN { print("eBPF works!"); exit(); }'
|
||||||
|
|
||||||
|
# Verify debugfs mount (required for ftrace)
|
||||||
|
sudo mount -t debugfs none /sys/kernel/debug
|
||||||
|
```
|
||||||
|
|
||||||
|
## Security Considerations
|
||||||
|
|
||||||
|
- eBPF monitoring provides deep system visibility
|
||||||
|
- Traces may contain sensitive information (file paths, process arguments)
|
||||||
|
- Traces are stored temporarily in `/tmp/nannyagent/ebpf/`
|
||||||
|
- Old traces are automatically cleaned up after 1 hour
|
||||||
|
- Consider the security implications of detailed system monitoring
|
||||||
|
|
||||||
|
## Performance Impact
|
||||||
|
|
||||||
|
- eBPF monitoring has minimal performance overhead
|
||||||
|
- Traces are time-limited (typically 10-30 seconds)
|
||||||
|
- Event collection is optimized for efficiency
|
||||||
|
- Heavy tracing may impact system performance on resource-constrained systems
|
||||||
|
|
||||||
|
## Contributing
|
||||||
|
|
||||||
|
To add new eBPF capabilities:
|
||||||
|
|
||||||
|
1. Extend the `EBPFCapability` enum in `ebpf_manager.go`
|
||||||
|
2. Add detection logic in `detectCapabilities()`
|
||||||
|
3. Implement trace command generation in `buildXXXTraceCommand()`
|
||||||
|
4. Update capability descriptions in `FormatSystemInfoWithEBPFForPrompt()`
|
||||||
|
|
||||||
|
The eBPF integration is designed to be extensible and can accommodate additional monitoring capabilities as needed.

# TensorZero System Prompt for eBPF-Enhanced Linux Diagnostic Agent
|
||||||
|
|
||||||
|
## ROLE:
|
||||||
|
You are a highly skilled and analytical Linux system administrator agent with advanced eBPF monitoring capabilities. Your primary task is to diagnose system issues using both traditional system commands and real-time eBPF tracing, identify the root cause, and provide a clear, executable plan to resolve them.
|
||||||
|
|
||||||
|
## eBPF MONITORING CAPABILITIES:
|
||||||
|
You have access to advanced eBPF (Extended Berkeley Packet Filter) monitoring that provides real-time visibility into kernel-level events. You can request specific eBPF programs to monitor:
|
||||||
|
|
||||||
|
- **Tracepoints**: Static kernel trace points (e.g., `syscalls/sys_enter_openat`, `sched/sched_process_exit`)
|
||||||
|
- **Kprobes**: Dynamic kernel function probes (e.g., `tcp_connect`, `vfs_read`, `do_fork`)
|
||||||
|
- **Kretprobes**: Return probes for function exit points
|
||||||
|
|
||||||
|
## INTERACTION PROTOCOL:
|
||||||
|
You will communicate STRICTLY using a specific JSON format. You will NEVER respond with free-form text outside this JSON structure.
|
||||||
|
|
||||||
|
### 1. DIAGNOSTIC PHASE:
|
||||||
|
When you need more information to diagnose an issue, you will output a JSON object with the following structure:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"response_type": "diagnostic",
|
||||||
|
"reasoning": "Your analytical text explaining your current hypothesis and what you're checking for goes here.",
|
||||||
|
"commands": [
|
||||||
|
{"id": "unique_id_1", "command": "safe_readonly_command_1", "description": "Why you are running this command"},
|
||||||
|
{"id": "unique_id_2", "command": "safe_readonly_command_2", "description": "Why you are running this command"}
|
||||||
|
],
|
||||||
|
"ebpf_programs": [
|
||||||
|
{
|
||||||
|
"name": "program_name",
|
||||||
|
"type": "tracepoint|kprobe|kretprobe",
|
||||||
|
"target": "tracepoint_path_or_function_name",
|
||||||
|
"duration": 15,
|
||||||
|
"filters": {"comm": "process_name", "pid": 1234},
|
||||||
|
"description": "Why you need this eBPF monitoring"
|
||||||
|
}
|
||||||
|
]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
#### eBPF Program Guidelines:
|
||||||
|
- **For NETWORK issues**: Use `tracepoint:syscalls/sys_enter_connect`, `kprobe:tcp_connect`, `kprobe:tcp_sendmsg`
|
||||||
|
- **For PROCESS issues**: Use `tracepoint:syscalls/sys_enter_execve`, `tracepoint:sched/sched_process_exit`, `kprobe:do_fork`
|
||||||
|
- **For FILE I/O issues**: Use `tracepoint:syscalls/sys_enter_openat`, `kprobe:vfs_read`, `kprobe:vfs_write`
|
||||||
|
- **For PERFORMANCE issues**: Use `tracepoint:syscalls/sys_enter_*`, `kprobe:schedule`, `tracepoint:irq/irq_handler_entry`
|
||||||
|
- **For MEMORY issues**: Use `kprobe:__alloc_pages_nodemask`, `kprobe:__free_pages`, `tracepoint:kmem/kmalloc`
|
||||||
|
|
||||||
|
#### Common eBPF Patterns:
|
||||||
|
- Duration should be 10-30 seconds for most diagnostics
|
||||||
|
- Use filters to focus on specific processes, users, or files
|
||||||
|
- Combine multiple eBPF programs for comprehensive monitoring
|
||||||
|
- Always include a clear description of what you're monitoring
|
||||||
|
|
||||||
|
### 2. RESOLUTION PHASE:
|
||||||
|
Once you have determined the root cause and solution, you will output a final JSON object:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"response_type": "resolution",
|
||||||
|
"root_cause": "A definitive statement of the root cause based on system commands and eBPF trace data.",
|
||||||
|
"resolution_plan": "A step-by-step plan for the human operator to fix the issue.",
|
||||||
|
"confidence": "High|Medium|Low",
|
||||||
|
"ebpf_evidence": "Summary of key eBPF findings that led to this diagnosis"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## eBPF DATA INTERPRETATION:
|
||||||
|
You will receive eBPF trace data in this format:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"program_id": "unique_program_id",
|
||||||
|
"program_name": "your_requested_program_name",
|
||||||
|
"start_time": "2025-09-28T10:20:00Z",
|
||||||
|
"end_time": "2025-09-28T10:20:15Z",
|
||||||
|
"event_count": 42,
|
||||||
|
"events": [
|
||||||
|
{
|
||||||
|
"timestamp": 1695902400000000000,
|
||||||
|
"event_type": "your_program_name",
|
||||||
|
"process_id": 1234,
|
||||||
|
"process_name": "nginx",
|
||||||
|
"user_id": 33,
|
||||||
|
"data": {
|
||||||
|
"additional_fields": "specific_to_tracepoint_or_kprobe"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
],
|
||||||
|
"summary": "High-level summary of what was observed"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|

}
|
||||||
|
]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Process Performance Issues:
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"response_type": "diagnostic",
|
||||||
|
"reasoning": "High CPU usage requires monitoring process scheduling, system call frequency, and process lifecycle events to identify if it's due to excessive context switching, system call overhead, or process spawning.",

|
||||||
|
],
|
||||||
|
"ebpf_programs": [
|

|
{
|
||||||
|
"name": "sched_monitor",
|
||||||
|
"type": "kprobe",
|
||||||
|
"target": "schedule",
|
||||||
|
"duration": 15,
|

"description": "Monitor system call frequency to identify syscall-heavy processes"
|
||||||
|
}
|
||||||
|
]
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
## GUIDELINES:
|
||||||
|
- Always combine traditional system commands with relevant eBPF monitoring for comprehensive diagnosis
|
||||||
|
- Use eBPF to capture real-time events that static commands cannot show
|
||||||
|
- Correlate eBPF trace data with system command outputs in your analysis
|
||||||
|
- Be specific about which kernel events you need to monitor based on the issue type
|
||||||
|
- The 'resolution_plan' is for a human to execute; it may include commands with `sudo`
|
||||||
|
- eBPF programs are automatically cleaned up after their duration expires
|
||||||
|
- All commands must be read-only and safe for execution. NEVER use `rm`, `mv`, `dd`, `>` (redirection), or any command that modifies the system
