consumes huge harddisk space and memory

[gsenthil]

We have installed cacti Version 0.8.7b in RHEL-3, RRD Tool 1.2.x
After installation and polling the device, hard disk and memory space consumed is given below
----------------------------------------------------------------

Please any body help us, how to controll the consumption of hard disk space and memory consumption

[Linegod]

For hard drive space, check your log level (don't keep it on debug), and rotate your log via logrotate.d

As for memory, can you go to 'Utilities/System Utilities/Technical Support' and cut and paste that into a 'code' block in this thread.

Note: It would make it a lot easier to read if you put your df and free commands into code blocks as well...

Thank you very Much, we have enabled the rotatelog we will monitor it ....
Please find the df & free command and also find the techsupport details in attachment, Please let us know wy there is huge memory consumption

Everything looks fine in your config.

please attach (as a text file) the output of:

Code: Select all

ps axfv

You can simply do:

Code: Select all

ps axfv >output.txt

Also check that mysql isn't generating binlogs - these are what used to fill up my Cacti server from time to time.

xdiskusage, xdu or FileLight are your friends for figuring out where it all went

[gsenthil]

Dear Linegod please find the output of the
ps axfv >output.txt as attachment

For Hard Disk storage.... first of all, maybe u need to check which one is hogging up the space.

U can use either "KDirStat" or "FileLight" to scan your hard disk and see which one is taking up the space.

Since your is RHELv3, here is the link to download:

KDirStat
ftp://ftp.pbone.net/mirror/dag.wieers.c ... g.i386.rpm
ftp://ftp.pbone.net/mirror/dag.wieers.c ... x86_64.rpm

FileLight
ftp://ftp.pbone.net/mirror/dag.wieers.c ... f.i386.rpm
ftp://ftp.pbone.net/mirror/dag.wieers.c ... x86_64.rpm

[Linegod]

Please run the following commands:

Code: Select all

echo "PRE" >output2.txt; df >>output.txt; free >>output2.txt; ps axfv >>output2.txt

Then turn off X Windows on the Linux box (init 3) and at a terminal console, do the following:

Code: Select all

echo "POST" >>output2.txt; df >>output.txt; free >>output2.txt; ps axfv >>output2.txt; 'du' /var/lib/mysql|sort -n >>output2.txt;  'du'  /www/htdocs/cacti/ |sort -n >>output2.txt

Then attach that file.
