When you increase the number of munin nodes, as well as increasing the number of plugins on each node, you will at the same time increase the risk of munin-update not being able to finish in 5 minutes. The other scripts, munin-limits, munin-graph, and munin-html can wait if needed, but for munin to have correct data, munin-update must be able to finish. Therefore I am very reluctant to increase the _default_ wait time for a plugin to respond, that should be a site local decision. The defaults should be safe and conservative. Another tip: When scaling munin, you good results if you spend a bit of time to put longer-running plugins in cron, and getting munin-node to quickly get the results from file. The less time and resources munin spends waiting for its nodes, the better. The "apt" plugin is a good example of this. -- Stig Sandbeck Mathisen, Linpro -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
