All CPU graph Black 100% or Blank

[Kurtou74]

Hi Mates,

Version of cacti : cacti-1.2.22

I'm encountering a problem on cacti with my CPU graphs, everthing turn to black 100% or Blank

You can see in attachment an example from one server, it was working before.. only CPU encountering an issue.

i tried the OID from the cacti server to my linux client with snmpwalk, seems no problem at all.

[root@XXXXXX ~]# snmpwalk -v 2c -c public XXXXX .1.3.6.1.4.1.2021.11.52.0
UCD-SNMP-MIB::ssCpuRawSystem.0 = Counter32: 1383738077
[root@XXXXXX ~]# snmpwalk -v 2c -c public XXXXX .1.3.6.1.4.1.2021.11.54.0
UCD-SNMP-MIB::ssCpuRawWait.0 = Counter32: 966256650

I'm using from datasources :

ucd_ssCpuRawIdle
ucd_ssCpuRawNice
ucd_ssCpuRawSystem
ucd_ssCpuRawUser
ucd_ssCpuRawWait

Thanks in advance for your feedback if you have any idea..

For some reason.. i found the problem was Min and Max values who were setted to 0 instead of U... why .. i don't know..

Do you know guys who to update all my datasources already setted and indexed from all servers without deleting and recreating everything ?

I tried something like that but it doesn't work..

for i in `cat /tmp/client.txt` ; do
/bin/rrdtool tune /cac0x00/prd/local/cacti-1.2.22/rra/$i_ucd_sscpurawidle_*.rrd --minimum ucd_ssCpuRawIdle:U

Solved myself

for addr in $(cat /tmp/client.txt)
do
/bin/rrdtool tune /cac0x00/prd/local/cacti-1.2.22/rra/"$addr"_ucd_sscpurawidle_*.rrd --minimum ucd_ssCpuRawIdle:U
/bin/rrdtool tune /cac0x00/prd/local/cacti-1.2.22/rra/"$addr"_ucd_sscpurawidle_*.rrd --maximum ucd_ssCpuRawIdle:U

Use rrdtool info command to see the data source names.
