A few questions about monitoring with Munin

Question

System administration

I'm thinking of using munin to monitor my servers. I set everything up as it should and I get such beautiful graphs:

There are several questions that I would like to discuss with you:

1. Default graphs show statistics for the day, week, month, year. How to make a graph by hours, minutes?
2. Again, by default, charts are updated every 5 minutes, is it possible to reduce this interval, say, to 1 minute. how this will affect the performance of munin,

Thanks for the answers.

Answer 1

1. What version of munin are you using? If the latter, then you can set up dynamic output of graphs via cgi . Then it will be possible to select statistics for any period of time.
2. You can change the interval through the cron settings (/etc/cron.d/munin). And how much this will affect the load - then look at the munin graphs. He knows how to measure his own performance.
