Hi all,

I had installed a MRTG on a Mandriva server more than a year ago, and
all went well. I tried recently with the exact same configuration on a
new server, and I miserably failed so I'm afraid I need your assistance.

I have written a minimal /var/www/html/mrtg/mrtg.cfg (below) and when I
run mrtg I get:

- ------------------------------------------------------------------------
# env LANG=C /usr/bin/mrtg /var/www/html/mrtg/mrtg.cfg
Unknown SNMP var ssCpuRawUser.0
 at /usr/bin/mrtg line 2035
Unknown SNMP var ssCpuRawIdle.0
 at /usr/bin/mrtg line 2035

Wednesday, 22 November 2006 at 10:51: ERROR:

- ------------------------------------------------------------------------

However:
 * the Target[server.estabcons] graphics are generated OK

 * I checked: # ll /usr/share/snmp/mibs/UCD-SNMP-MIB.txt
- -rw-r--r-- 1 root root 35242 Aug 15 21:51
/usr/share/snmp/mibs/UCD-SNMP-MIB.txt
# grep ssCpuRawUser /usr/share/snmp/mibs/UCD-SNMP-MIB.txt
ssCpuRawUser OBJECT-TYPE

 * I checked: $ snmpget -v1 -c public localhost ssCpuRawUser.0
UCD-SNMP-MIB::ssCpuRawUser.0 967624


I'm stuck. Any hint welcome.

Have a nice day,

Camille.
