Peformance Data in a Database

[Ben Clewett]

Hi Chris,

The problem of simply getting the performance data into a MySQL table is 
not that complex.  I have suggested this line of UNIX script will do 
this as-is:

tail -f /usr/local/nagios/var/serviceperf.log | awk -F"\t" '{ print 
"INSERT INTO service_performance (hostname, servicename, time, output, 
perfdata) values (\"" $2 "\", \"" $3 "\", from_unixtime(\"" $1 "\"), \"" 
$4 "\", \"" $5 "\");" }' | mysql -u nagios -pnagios -D nagios -h localhost

But sensibly this does not address several problems:
-	Handling the zero, one or many metrics of performance data from each 
line of data, extracting the true figures.
-	Patching Nagios to use this data for it's own use.  Ie, hystergrams of 
past performance.  (Or a great idea I think: projected figures for 
estimated time of failure, using one of many exciting algorithms.)
-	Including this as a patch on MySQL.

Looking at the excellent work Druzhinin Eugene has done along these 
lines, this is a much bigger project than I had originally thought.

What I would like to do is complete this in two iterations.  Firstly, a 
robust parser, as above but properly written.  Designed using nagios 
libraries, config files, nagios mysql handler.  Also to take each line 
cold so that this can be used as a line-by-line parser.

Secondly, if it works and is liked, to patch Nagios with this work and 
offer it to those who are, for those that would like.

If I get a working parser, I'll post a link.

Regards, Ben.
