Hi all,
is there a simple tool to monitor high system loads and outages in debian?
For me, it would be completely sufficient if there would be a tool
that samples every minute or every few minutes (e.g. in a cron job)
the system load and reports any issues to the user in a simple way
like this:
day > load 5 | > load 10 | > load 15 | DOWN
------------------------+-------------+-------------+----------
26.01. 6.31% | 1.20% | 0.53% | 0.00%
27.01. 6.31% | 1.20% | 0.53% | 0.00%
28.01. 6.31% | 1.20% | 0.53% | 0.00%
29.01. 6.31% | 1.20% | 0.53% | 4.43%
30.01. 6.31% | 1.20% | 0.53% | 0.00%
------------------------+-------------+-------------+----------
Average: 6.31% | 1.20% | 0.53% | 1.31%
Purpose is to get an overview about the "performance" of the server
provider in case of "sandbox" vservers, so where I would not be aware
of any issues like the server is not available some hours during
nighttime for example.
I have started writing such a program in perl, it works great but
monitors only real downtimes at the moment, so not by system load as
the figure above indicates.
