# Internal Input Plugin
|
||
|
|
|
||
|
|
The `internal` plugin collects metrics about the telegraf agent itself.
|
||
|
|
|
||
|
|
Note that some metrics are aggregates across all instances of one type of
|
||
|
|
plugin.
|
||
|
|
|
||
|
|
### Configuration:
|
||
|
|
|
||
|
|
```toml
|
||
|
|
# Collect statistics about itself
|
||
|
|
[[inputs.internal]]
|
||
|
|
## If true, collect telegraf memory stats.
|
||
|
|
# collect_memstats = true
|
||
|
|
```
|
||
|
|
|
||
|
|
### Measurements & Fields:
|
||
|
|
|
||
|
|
memstats are taken from the Go runtime: https://golang.org/pkg/runtime/#MemStats
|
||
|
|
|
||
|
|
- internal\_memstats
|
||
|
|
- alloc\_bytes
|
||
|
|
- frees
|
||
|
|
- heap\_alloc\_bytes
|
||
|
|
- heap\_idle\_bytes
|
||
|
|
- heap\_in\_use\_bytes
|
||
|
|
- heap\_objects\_bytes
|
||
|
|
- heap\_released\_bytes
|
||
|
|
- heap\_sys\_bytes
|
||
|
|
- mallocs
|
||
|
|
- num\_gc
|
||
|
|
- pointer\_lookups
|
||
|
|
- sys\_bytes
|
||
|
|
- total\_alloc\_bytes
|
||
|
|
|
||
|
|
agent stats collect aggregate stats on all telegraf plugins.
|
||
|
|
|
||
|
|
- internal\_agent
|
||
|
|
- gather\_errors
|
||
|
|
- metrics\_dropped
|
||
|
|
- metrics\_gathered
|
||
|
|
- metrics\_written
|
||
|
|
|
||
|
|
internal\_gather stats collect aggregate stats on all input plugins
|
||
|
|
that are of the same input type. They are tagged with `input=<plugin_name>`.
|
||
|
|
|
||
|
|
- internal\_gather
|
||
|
|
- gather\_time\_ns
|
||
|
|
- metrics\_gathered
|
||
|
|
|
||
|
|
internal\_write stats collect aggregate stats on all output plugins
|
||
|
|
that are of the same input type. They are tagged with `output=<plugin_name>`.
|
||
|
|
|
||
|
|
|
||
|
|
- internal\_write
|
||
|
|
- buffer\_limit
|
||
|
|
- buffer\_size
|
||
|
|
- metrics\_written
|
||
|
|
- metrics\_filtered
|
||
|
|
- write\_time\_ns
|
||
|
|
|
||
|
|
internal\_\<plugin\_name\> are metrics which are defined on a per-plugin basis, and
|
||
|
|
usually contain tags which differentiate each instance of a particular type of
|
||
|
|
plugin.
|
||
|
|
|
||
|
|
- internal\_\<plugin\_name\>
|
||
|
|
- individual plugin-specific fields, such as requests counts.
|
||
|
|
|
||
|
|
### Tags:
|
||
|
|
|
||
|
|
All measurements for specific plugins are tagged with information relevant
|
||
|
|
to each particular plugin.
|
||
|
|
|
||
|
|
