problem with measuring teroctet disk space

[Patrick_C]

Hello,

I am having troubles with zabbix v1.4.4 measuring total disk space and free disk space on a Windows Server 2003.
It seems that zabbix is not able to measure disk space higher than a teraoctet.

Is there anybody having knowledge on this kind of problem?

It looks like it might be the database side. If I look at my mysql database table 'history' for zabbix it shows that the history field is DOUBLE(16,4) - this means 16 digits (up to 4 go after the decimal point) for octets.

This means a max of 9,999,999,999,999,999. Just short of 10 petaoctet if I'm correct. I don't know too much about numeric types though, so it could be lower requiring at least 1 decimal point - i.e. 999,999,999,999,999.9 - just short of 1 petaoctet.

In order to record a value higher than that the database would need to be adjusted, however there might be other circumstances which would still restrict it - e.g binary might not support larger numbers, php might need adjusting, other tables might need to be adjusted.

Thank you for your help.
To change this type I have to modify the source code and to recompile zabbix, right? Or can it be done by configuring zabbix?

1.6.5 doesnt seems to resolve the problem

I've decided to migrate to 1.6.5 version after having found the ZBX-93 bug report.
But the database upgrade doesn't change the column size of value field in history table. It still is (16,4).
Since I haven't large HD (>1Tbyte to reproduce the problem) I cannot check the resolution of the problem.

Does anyone measure >1TByte disk space with Zabbix 1.6.5? or with other versions?

regards

PS: teraoctet=terabyte

You can try to receive the value from the command-line with zabbix_get -s <target> -k <key> and see what it returns.

This way you can check if it fits into the database.
