Monitoring by Rest Api
This article describes how to get the internal Fluentd metrics via REST API.
Fluentd has a monitoring agent to retrieve internal metrics in JSON via HTTP. Please add the following lines to your configuration file.
<source>
@type monitor_agent
bind 0.0.0.0
port 24220
</source>
Next, please restart the agent and get the metrics via HTTP.
$ curl http://host:24220/api/plugins.json
{
"plugins":[
{
"plugin_id":"object:3fec669d6ac4",
"type":"forward",
"output_plugin":false,
"config":{
"type":"forward"
}
},
{
"plugin_id":"object:3fec669dfa48",
"type":"monitor_agent",
"output_plugin":false,
"config":{
"type":"monitor_agent",
"port":"24220"
}
},
{
"plugin_id":"object:3fec66aead48",
"type":"forward",
"output_plugin":true,
"buffer_queue_length":0,
"buffer_total_queued_size":0,
"retry_count":0,
"config":{
"type":"forward",
"host":"192.168.0.11"
}
}
]
}
Since v0.12.17,
monitor_agent
plugin has tag
parameter. If you set tag monitor.metrics
, monitor_agent
plugin emits internal metrics to monitor.metrics
tag. Here is an example with stdout
