# Suricata Input Plugin
|
|
|
|
This plugin reports internal performance counters of the Suricata IDS/IPS
|
|
engine, such as captured traffic volume, memory usage, uptime, flow counters,
|
|
and much more. It provides a socket for the Suricata log output to write JSON
|
|
stats output to, and processes the incoming data to fit Telegraf's format.
|
|
|
|
### Configuration
|
|
|
|
```toml
|
|
[[input.suricata]]
|
|
## Data sink for Suricata stats log.
|
|
# This is expected to be a filename of a
|
|
# unix socket to be created for listening.
|
|
source = "/var/run/suricata-stats.sock"
|
|
|
|
# Delimiter for flattening field keys, e.g. subitem "alert" of "detect"
|
|
# becomes "detect_alert" when delimiter is "_".
|
|
delimiter = "_"
|
|
```
|
|
|
|
### Metrics
|
|
|
|
Fields in the 'suricata' measurement follow the JSON format used by Suricata's
|
|
stats output.
|
|
See http://suricata.readthedocs.io/en/latest/performance/statistics.html for
|
|
more information.
|
|
|
|
All fields are numeric.

#### Suricata configuration
|
|
|
|
Suricata needs to deliver the 'stats' event type to a given unix socket for
|
|
this plugin to pick up. This can be done, for example, by creating an additional
|
|
output in the Suricata configuration file:
|
|
|
|
```yaml
|
|
- eve-log:
|
|
enabled: yes
|
|
filetype: unix_stream
|
|
filename: /tmp/suricata-stats.sock
|
|
types:
|
|
- stats:
|
|
threads: yes
|
|
```
|
|
|
|
