[SOLVED] Better Linux memory usage graphs ?

[kriskaido]

Here it is :

Code: Select all

UCD-SNMP-MIB::memIndex.0 = INTEGER: 0
UCD-SNMP-MIB::memErrorName.0 = STRING: swap
UCD-SNMP-MIB::memTotalSwap.0 = INTEGER: 522104 kB
UCD-SNMP-MIB::memAvailSwap.0 = INTEGER: 435912 kB
UCD-SNMP-MIB::memTotalReal.0 = INTEGER: 1005480 kB
UCD-SNMP-MIB::memAvailReal.0 = INTEGER: 150168 kB
UCD-SNMP-MIB::memTotalFree.0 = INTEGER: 586080 kB
UCD-SNMP-MIB::memMinimumSwap.0 = INTEGER: 16000 kB
UCD-SNMP-MIB::memShared.0 = INTEGER: 0 kB
UCD-SNMP-MIB::memBuffer.0 = INTEGER: 36268 kB
UCD-SNMP-MIB::memCached.0 = INTEGER: 407592 kB
UCD-SNMP-MIB::memSwapError.0 = INTEGER: noError(0)
UCD-SNMP-MIB::memSwapErrorMsg.0 = STRING: 

Here's another funny graph

I think the graph template is corrupted...

Could you post a screenshot of it ?

Well, after checking quicky, I have the same problem with Cacti 0.8.7a :



With 0.8.6j, the CDEF (which calculates "used memory" with "total memory - shared - free - buffers) works fine :



I'll try to find why.

[exploit-soget]

Thanks a lot for your time and patience ...

[kormoc]

Awesome graph. Thanks very much!

Any idea on how hard (or where I should look) to add shared memory to the graphs?

It's not difficult to modify the templates, but on every server I have the value is 0

Have you some news (good ?) about the problem of this graph ?
I use it in a PRODUCTION environment and it is difficult to resolve this problem (i have try with the CDEF but in vain).

Please HEEELPPPP ...

Hi

I'll keep an eye on it tomorrow (I don't have access to my Cacti serves today).

[fmangeant]

Using this patch, the graph is working again

[kriskaido]

I'm not a patch guru, how do you apply it ?

Thanks !!

Kris.

[exploit-soget]

IT WORKS ! Thanks a lot.

See the instructions here.

You can also download pre-patched files there.

[kriskaido]

Perfect, thanks !
