Package: munin-node
Version: 1.2.2-2
Severity: normal
Hi,
The processing done by the apt_all plugin can be rather expensive if there
are many packages installed and/or many sources in sources.list. On one of
my systems the plugin even times out sometimes.
Since the results it obtains will always be the same anyway until apt-get
update is run again, why not move the processing there? Either write a file
into /var/cache with the output of the plugin from the apt-get update
cronjob; or maybe there is a mechanism to have apt invoke a program after
apt-get update, so the plugin output would also be updated on manual
apt-get updates.
The plugin itself would just need to cat the file from /var/cache.
Considering that the plugin gets run every five minutes or so, the savings
could be significant.
I file this report with a severity of 'normal' instead of 'wishlist' because
due to the timeout the plugin sometimes actually fails.
