[solved] munin not collecting data

Message

Hm, I had munin running on SuSE and don't remember any major setup. So I just emerge munin and ran emerge --config. The cronjob
actually runs every 5min but it doesn't seem to collect any data, the html page for my server stays empty.

So I had a look in /var/log/munin/munin-node.log:

Code: Select all

2006/07/11-20:20:01 CONNECT TCP Peer: "127.0.0.1:34732" Local: "127.0.0.1:4949" 
2006/07/11-20:20:01 [21148] TLS Notice: No key file "/etc/munin/munin-node.pem". Continuing without private key. 
2006/07/11-20:20:01 [21148] TLS Notice: No certificate file "/etc/munin/munin-node.pem". Continuing without certificate.

Hm, strange ports, is this the cronjob? Anyway, what isthis certificate stuff about and may this be the cause why no data is collected?

Code: Select all

# munin-node-configure --shell

I'm having the same problem, but running munin-node-config --shell did
not fix it. Do you have any other tips? My html pages is turning up all empty.

Same problem here: munin-node.log is full of these:

Got it working. I had 'ssl' enabled in USE flags. And this caused the line 'tls disabled' to be missing from munin-node.conf

By adding the line 'tls disabled' to munin-node.conf seemed to help.

Hey, I seem to be having the same problem with munin 1.3.2 and it seems as if the munin-cron job contacts munin-node and gets some sort of data, but never puts it on a graph. I tried the solution suppled by the previous posters(I was getting the same error messages) but it doesn't seem to fix anything. I am getting graphs with absolutely no data on them. I see weird greenish dots on the bottom of the graph and the information below the graphs all say 0.00.

I know munin-node is working correctly because all I had to do was type

Code: Select all

munin-run df

and it spewed out the correct numbers.

Anyone have any ideas?
