Troubleshooting issues with Telegraf package?

victorhooi

Hi,

I have a Netgate XG-7100 running 2.4.4-p2.

I've installed the official Telegraf package, and put in my Telegraf IP address, username and password.

I then restarted the pfSense device.

On restart, I checked /var/log/telegraf.log - it contains a single line:

daemon: process already running, pid: 74273

However, no data appears to be written out yet to the target InfluxDB database.

Any tips on how to troubleshoot it further?

Aha - I found the issue. I should have read the on-screen help text =).

In the InfluxDB server field, you need to put the full protocol and port number - you can't just put the IP address (even if it's using the default InfluxDB port).

That being said - still curious how to debug this - /var/log/telegraf.log still only has a single line. Not sure why nothing is being logged?

daemon: process already running, pid: 74273

I found one troubleshooting tip based on an earlier post:

https://forum.netgate.com/topic/129002/telegraf-memory-stats-broken-on-2-4-3

From CLI on the pfSense box, you can run:

/usr/local/bin/telegraf -config=/usr/local/etc/telegraf.conf --test

For example:

[2.4.4-RELEASE][admin@ang-router.localdomain]/root: /usr/local/bin/telegraf -config=/usr/local/etc/telegraf.conf --test
