Hello,
Sidecar is just a wrapper for “Winlogbeat, FileBeat, MetricBeat, Nxlog”, you can install these separate.
Example for Nxlog you can use this to pick up MongoDb Slow Query logs
<Input in>
Module im_file
FILE "/var/log/mongodb/mongodb_slow.log"
SavePos TRUE
ReadFromLast TRUE
PollInterval 1
Exec $Message = $raw_event;
</Input>
or FileBeat
filebeat.inputs:
- input_type: log
paths:
- /var/log/mongodb/mongodb_slow.log
type: log
Hope that helps
