Percona Load Average empty graph

Archived Projects Percona Monitoring Plugins

Hi,

On debian wheezy, I’ve installed cacti “0.8.8a” and the percona cacti template “1.0.4” :

Everything is fine except for the Percona Load Average graph (empty with -nan value for Cur/Avg/Max)

The script ss_get_by_ssh.php get the correct value :

/usr/bin/php -q /usr/share/cacti/site/scripts/ss_get_by_ssh.php --host 10.0.0.2 --type w --items ho
ho:2,00

No errors in the error log.

Any idea ?

Thanks in advance.

What’s the output of “w” command on the server?

It should look like:
21:26 up 22 days, 1:04, 6 users, load averages: 0.83 0.81 0.78

But it seems, in your case, the load average reports numbers containing , (comma) as a decimal delimiter, may be due to the locale. That’s a problem.
