The "stats" RPC command can be used by external processes to query statistics, such as traffic counters. This is useful for diagnostics, monitoring and display in admin consoles.
Statistics are optionally logged to separate text files.
For implementations details, please see Statistics API
All configuration nodes and values are optional, with the default values shown in comments below:
"node": {
...
"statistics": {
// Sampling configuration (optional)
"sampling": {
"enabled": "true", // If sampling is enabled. Default false.
"capacity": "5", // How many samples to keep. Must be set if sampling is enabled.
"interval": "1000" // Sample interval in milliseconds. Must be set if sampling is enabled.
},
// File logging (optional)
"log": {
"interval_counters": "5000", // How often to write counters to file in milliseconds. Default 0 (off)
"interval_samples": "5000", // How often to write samples to file, milliseconds. Default 0 (off)
"rotation_count": "5", // Rotate file after writing statistics this many times. Default 100.
"headers": "true", // Write header containing log
"filename_counters": "counters.stat",
"filename_samples": "samples.stat"
}
}
