Sorry for reading your post too late

I'm not using 5.4 everywhere, for example extending the agent does not work any more for me on AIX 64 bits...

Don't worry, I managed the issue on my own. Have a nice week end.

Hi

most of the time (at least on my servers) the includeAllDisks option does not work. Could you replace it with something like this :
Code:
disk /
disk /usr
disk /var

Hi

I replaced includeAllDisk with this:

Code:

disk /


and restart the snmp service: "service snmpd restart", and i got this:

Code:

$ snmpwalk -v 1 -c public tcp:localhost:161 dskPath
End of MIB
$ snmpget -v 1 -c public tcp:localhost:161 dskPath
Error in packet
Reason: (noSuchName) There is no such variable name in this MIB.
Failed object: UCD-SNMP-MIB::dskPath


Any idea?, thanks

Code:
agentaddress tcp:161
rocommunity public
disk /

My net-snmp agent dont work when i click in Verbose Query to get informations to my processors. I just click and before 5 minutes my webserver returns error 500: internal error server, in my server, show a loop process to /usr/bin/php -q
/home/xxx/www/cacti/scripts/ss_host_cpu.php ... shows it:
Code:
[root@svr02 ~]# /usr/bin/php -q /home/sigfbr/public_html/cacti/scripts/ss_host_disk.php xxx.xxx.xxx.xxx 6 2:161:500:public:::MD5::DES: index
No log handling enabled - turning on stderr logging
Cannot find module (MTA-MIB): At line 0 in (none)
Cannot find module (NETWORK-SERVICES-MIB): At line 0 in (none)
Cannot find module (LM-SENSORS-MIB): At line 0 in (none)


In my other server with net-snmp 5.3.1 this not happen...

Can anyone compile a version 5.4 to linux centos (fedore core 6) and attach here to me??

Can you :
  • update Net-SNMP to version 5.3.1-15 (available here) on your Fedora Core 6 box ?
  • unset the MIBS variable on your Cacti server ?

Try that :
Code:
$ unset MIBS
$ /usr/bin/php -q /home/sigfbr/public_html/cacti/scripts/ss_host_disk.php xx.xx.xx.xx 6 2:161:500:public:::MD5::DES: index

By the way, maybe you should remove your IP address from your previous post.

I have same problem with 0.8.7a.

This is my 0.8.7a with revision 4371:
Code:

[root@svr02 snmp]# /usr/bin/php -q /home/sigfbr/public_html/cacti/scripts/ss_host_cpu.php localhost 2 2:161:500:public:::MD5::DES: index

[root@svr02 snmp]#


and my 0.8.7a:
Code:

[root@svr02 snmp]# /usr/bin/php -q /home/sigfbr/public_html/cacti2/scripts/ss_host_cpu.php localhost 2 2:161:500:public:::MD5::DES: index
[root@svr02 snmp]#


if I check my other server with old cacti (0.8.7):
Code:

root@svr03 [/home/admin]# /usr/bin/php -q /home/sysmon/public_html/cacti/scripts/ss_host_cpu.php localhost 2 2:161:500:public:::MD5::DES: index
0
1
2
3
root@svr03 [/home/admin]#


my snmpd.conf is the same for all my servers

Code:

[root@svr02 snmp]# cat snmpd.conf

rocommunity public
syslocation ForBrazil - SvrXX
syscontact roberto@forbrazil.com.br
# dontPrintUnits true
includeAllDisks 10%
