R: [hobbit] RE [hobbit] Database test: dbcheck.pl on deadcat and sourceforge

[Francesco Duranti]

The script will monitor all the database from a single host that have access to the database and the database client installed. The better thing to do is to run them on the server where you have all the configuration of hobbit in a unique place but it can also be run on a client (not tested but should work). 
To run them you can use the hobbitlaunch.cfg or clientlaunch.cfg (if you're running on a client).

To do all the check i use 2 section in the hobbitlaunch.cfg of the hobbit server to check the database with different timing. 
I use to launch a fast check every 5 minutes that will only check for connection, audit table, tablespace, session and cache (because i graph them and i want the 5 minutes data) and a slow test that do the rest of the check (rollback and extent check on some of the database I'm checking take 10-15 minutes to run so i prefer to run them every 4 hour).

[dbfast]
        ENVFILE /home/bbtest/server/etc/hobbitserver.cfg
        NEEDS hobbitd
        CMD $BBHOME/ext/dbcheck.pl fast
        LOGFILE $BBSERVERLOGS/bb-dbfast.log
        INTERVAL 5m
[dbslow]
        ENVFILE /home/bbtest/server/etc/hobbitserver.cfg
        NEEDS hobbitd
        CMD $BBHOME/ext/dbcheck.pl slow
        LOGFILE $BBSERVERLOGS/bb-dbslow.log
        INTERVAL 240m

I will check for the 2 problem you got. If you not did it try to run bbcmd dbcheck.pl instead of running directly the command (or launch bbcmd bash and then run the ./dbcheck.pl). I also got a problem on the extent check, a new version will be available during this week to solve those problems and to add some documentation :D

Thanks for the report

Francesco

Hello Francesco !

Thans for all your scripts and work ! It looks amazing... However I don't understand the way it works. Sorry.... I'm talking about the dbcheck test. Here are my questions :

- These scripts have to be executed on the hobbit server or on Hobbit clients ?
- In both cases,  have we to setup hobbitlaunch.cfg or clientlaunch.cfg to run the check ?
- I'm running Hobbit v4.1.2p1 and when launching dbcheck.pl I got this output : 

        [hobbit at psu155 ext]$ ./dbcheck.pl 
        Use of uninitialized value in concatenation (.) or string at ./dbcheck.pl line 806.
        Use of uninitialized value in concatenation (.) or string at ./dbcheck.pl line 78.
        Could not open the disabled hosts directory: No such file or directory
        Could not close the DISABLED directory handle: No such file or director

 I commented out corresponding lines and these warnings disappear.

Thanks again for all your hard work !
Best regards,

Thomas
