Check old data from logs

[Carroll, Jim P [Contractor]]

Good point, I'd neglected to suggest the following (which I've yet to dabble
in myself):

- configure nagios to use serviceperf.log:
  - in nagios.cfg, add this:

    xpdfile_service_perfdata_file=/usr/local/nagios/var/serviceperf.log

  - rebuild nagios binaries, thus:

    ./configure --with-file-perfdata
    make

- install MySQL

- write a Perl script (and implement it with cron) to slurp serviceperf.log,
parse the rows you're interested in, and stuff them into a MySQL table

- install PHP if you haven't already

- install JpGraph

- write some PHP code to:
  - slurp relevant rows from MySQL
  - dynamically create graphs using JpGraph

Food for thought.

Nagios does not store each check natively. There are several options
however:

1) Apan might work for you.
2) write an OCSP command that store the data how you want it.
3) use a postgres backend and have a trigger copy the data to a
service-history type of table on insert or update from nagios.

I'm sure there are other options. We use the third and its been very
effective.

Is there a way for me to see what the previous check values were for a
service check?

So I have a service check of my memory usage every 15 minutes.  Say I
want to look back at the last 24 hours and see the value of all the
checks every 15 minutes.

If I look at "Availability Report" it will say like 2HRS OK then 4HRS OK
and give me the initial value but not the values during those 2 hours or
4 hours.

If I look at notification alerts, it will only give me the values that
were emailed to me on change of status.  I do not want to add more
emails to myself and have nagios email me every 15 minutes if the
service is OK.

Is there another way to do what I want?
