I am using Cacti (0.8.7g) to monitor 8 hosts (HP blade server running RHEL5.3).
I was originally running Cacti on one of the blades, but have moved it onto a different server (Solaris x86 - use for all stats and reporting).
It was all working fine on the RedHat machine, but on the Solaris box I am having problems with disk space reporting. I am using the "Host MIB - Hard Drive Space" data template.
Whenever ss_host_disk.php is run, I get a segmentation fault (in the SNMP call - see trace below). This causes two problems, firstly, I do not get any disk space reports (they all return zero), and secondly, when the host.php page is invoked in "edit" mode it causes PHP to crash.
All other SNMP based stats seem to be working fine, as is SNMP itself - see below for snmpget of the same disk space attribute.
I've managed to get this far with working out what's going on, but am stuck as to where the issue causing the Seg Fault lies.
Any ideas or suggestions would be greatly appreciated.
Cheers,
Chris Ford
