There is a list, fwiw, for users of this and related plugins, but it appears to be mostly dead... http://sourceforge.net/mailarchive/forum.php?forum_name=nagios-snmp-users ...so you're probably better off asking here. > i recently implemented it against solaris 9 and 10 running net-snmp 5.0.9: > > bash-3.00# /usr/sfw/sbin/snmpd -v > > NET-SNMP version: 5.0.9 > Web: http://www.net-snmp.org/ > Email: [EMAIL PROTECTED] > > unfortunately one of the OIDs doesn't answer: > > [EMAIL PROTECTED] libexec]# snmpget -v 1 -c mycommunity 1.2.3.4 " > 1.3.6.1.4.1.2021.4.15.0" > Error in packet > Reason: (noSuchName) There is no such variable name in this MIB. > Failed object: UCD-SNMP-MIB::memCached.0 > ... > I've snmpwalked but don't really understand why this oid fails (something > about solaris not using this concept of cached memory?). You're on the right track. Solaris and Linux have different memory management models - Solaris doesn't have the same concept of cached memory as does Linux, at least in a way that net-snmp knows about. See the description for this object from a more recent release of net-snmp: (from http://www.net-snmp.org/docs/mibs/ucdavis.html) | This object will not be implemented on hosts where the | underlying operating system does not explicitly identify | memory as specifically reserved for this purpose. > Does anyone know another oid i could query to get this value? Or perhaps > share a workaround/solution you may have found? Short of hacking that plugin a bit, you've got a couple of options - you could just check the corresponding objects (or just the ones of concern) directly using check_snmp. Considering what check_snmp_mem actually checks, you could also use check_snmp_storage, from the same author, and only look at Real memory and Swap, e.g.: [EMAIL PROTECTED] $plugins/check_snmp_storage.pl -H 1.2.3.4 -C mycommunity -m '^Swap|^Real' -w 75 -c 90 -S 0,1 -f Note that this is using a different mib (host-resources-mib) than check_snmp_mem (ucd-snmp-mib) and therefore _should_ be available and yield similar results across platforms. There are some caveats to using this mib, but for checking memory/swap usage, it should be fine.
