Hello I'm using Zenoss Core v2.4.2 and manage 100 devices (cisco routers) and more or less between 20000 and 21000 OID's requests.

After this information I have a little problem with the MySql DB into the path "/usr/local/zenoss/mysql/data" with the file "ibdata1", actually the size it to big:

# du -sh *
96K events
4.2G ibdata1 ------> How to shrink DB?
5.1M ib_logfile0
5.1M ib_logfile1
776K mysql
796K mysqld.log
4.0K test
4.0K zncsrvr.pid
#

How I can decrease or shrink this database file???

I'll apreciate all your comments

I am having the same trouble. I am at 17 gigs on my database. What can safely be done about getting this file under control?

take a look here if can be usefoul

My events database was growing a lot although I already had used the cleanupscripts of zenoss. Here is how to clean more.

Re: Problem with ibdata1 is growing up how can shrink??

another thing could also be to set a max size on the my.cnf , usually in /usr/local/zenoss/mysql
i.e
innodb_data_file_path = ibdata1:10M:autoextend:max:512M

or if you more generous.

innodb_data_file_path=ibdata1:10M:autoextend:max:15G

as i understand it with this, the database will never grow bigger than your max setting and old data will be lost whe max size is reached.

plz correct me if im wrong, im no mysql guru.

BTW:
Zope also has a database. should be packed now and then.
