LibreNMS portal working with InfluxDB

Help
1

Hi there,

I am going to play with LibreNMS with InfluxDB. I have read document: InfluxDB - LibreNMS Docs. LibreNMS will send data and rrd to InfluxDB. I would like to keep only one database.

  • Can we setup LibreNMS portal only use influxDB (drop mysql database)?
  • Is LibreNMS portal still using mysql, it is just sending replicate data to InfluxDB?

Thank you.

Regards

Hello. Yes, MySQL is required for LibreNMS. Pretty much all of the configuration for LMNS itself is stored in the MySQL DB. Since its metrics go to rrd, you can keep the MySQL DB reasonable small if you don’t store logs long term.
If you have a look at LibreNMS Docs - Metric storage you’ll see that when you configure InfluxDB or any of the TSDB’s you’re just telling LNMS to replicate/ship the metrics off to those DB’s.

Great, thanks for your reply. :slight_smile:
I have installed InluxDB on another server. And then enabled InfluxDB on config.php just like InfluxDB - LibreNMS Docs.

But My Bucket in InfluxDB is not receiving metrics from LibreNMS. Do I need to setup Telegraf plugin on InfluxDB server? or setup Telegraf plugin on LibreNMS server?

Thank you
