###### snmpd stuff

mib - management information base
subtree (object id) - .1.3.6.1.2.1; used to obtain specific information and control access
community - string which is used to access snmp data locally or over the network

/usr/share/snmpd/mibs - location of mibs on nodes

hrswrunpath - mib to obtain services
hrsystemuptime - mib to obtain host uptime & in Zabbix use float, uptime, multiplier .01
laLoad.{1..3} - mib for cpu loads 1, 5, and 15 minutes
memTotalReal - total memory available (case sensitive) & in Zabbix use float, bytes, multiplier 1024
memAvailReal - total RAM free
memTotalFree - total physical memory free
memTotalSwap - total swap memory
memAvailSwap - free swap memory

# get OID from MIB name
snmpwalk -O f -v 1 -c ....

# disk checks require snmpd.conf to have disk added
dskPath.{1..} - n is the disk identified within snmpd.conf; lists mountpoint i.e. /
dskDevice.{1..} - n is the disk identified within snmpd.conf; lists device
dskTotal.{1..} - lists total space of disk in kb (2 TB limitation, use % free)
dskUsed.{1..} - lists total space used in kb
dskPercent.{1..} - lists total percent of disk space used
dskPercentNode.{1..} - lists total percent of inodes used
diskIODevice.{1..} - lists all disk devices

# process checks
prEntry - get list of processes monitored configured via snmpd.conf
prNames.n - get name of process where n is integer value
prCount.n - get total processes based upon n

# using a shell command within snmpd.conf
snmpwalk -v 1 wh-mds-01 -c public .1.3.6.1.4.1.2021.8.n - n is command in snmpd.conf
snmpwalk -v 1 wh-mds-01 -c public extResult.1 - get error code
snmpwalk -v 1 wh-mds-01 -c public extOutput.1 - get output (such as fail|pass)

# powerconnect switches
snmpwalk -v 1 10.250.40.2 -c public 1.3.6.1.4.1 - all data (uses too much CPU on switch)
snmpwalk -v 1 10.250.40.2 -c public 1.3.6.1.4.1.674 - obtain quick device details
snmpwalk -v 1 10.250.40.2 -c public 1.3.6.1.4.1.674.10895.3000.1.2.100.4 - firmware revision

# get mac addresses on switch
# public string with VLAN may not be necessary
# convert hex to decimal for easy searching OR grep for part of MAC and then last three octets
snmpwalk -v 1 -c "rc.usf.edu@250" 10.247.4.115 .1.3.6.1.2.1.17.4.3 - @250 is VID within community string
snmpwalk -v 1 -c "rc.usf.edu@250" 10.247.4.114 .1.3.6.1.2.1.17.4.3.1.1 - just grab mac addresses
