[mrtg] Re: question about SNMP on Server

[Daniel R . Kilbourne]

For Linux : 

get snmp running on the machine - http://ucd-snmp.ucdavis.edu

then you can use the following OIDs

Linux Machines
.1.3.6.1.2.1.2.2.1.10.1                 Eth0 Input Stats
.1.3.6.1.2.1.2.2.1.16.1                 Eth0 Output Stats
.1.3.6.1.4.1.2021.4.5.0                 Total Available Memeory
.1.3.6.1.4.1.2021.4.6.0                 Total Used Memory
.1.3.6.1.4.1.2021.4.11.0                Total Free Memory
.1.3.6.1.4.1.2021.4.13.0                Shared Memory
.1.3.6.1.4.1.2021.4.14.0                Buffers
.1.3.6.1.4.1.2021.4.15.0                Cached
.1.3.6.1.4.1.2021.10.1.3.1              Load Average -1 Minute
.1.3.6.1.4.1.2021.10.1.3.2              Load Average -5 Minute
.1.3.6.1.4.1.2021.10.1.3.3              Load Average -15 Minute

here is a sample for eth, mem and cpu (my comments are in ()  )

Target[eth]: 3:community at server (I can never get the OID from above to work, so I just run cfgmaker on the server and use what it finds)
MaxBytes[eth]: 1250000
Title[eth]: server ether traffic
PageTop[eth]: server ether traffic
Options[eth]: bits
Legend1[eth]: Ether Traffic in
Legend2[eth]: Ether Traffic out
LegendI[eth]: Traffic in
LegendO[eth]: Traffic out

Target[mem-used]: 1.3.6.1.4.1.2021.4.6.0&1.3.6.1.4.1.2021.4.6.0:community at server
MaxBytes[mem-used]: 257884 (do an 'snmpget server community' .1.3.6.1.4.1.2021.4.5.0 to get this value)
Title[mem-used]: server RAM used
PageTop[mem-used]: server RAM used
Legend1[mem-used]: Total used RAM (MB)
Legend2[mem-used]:
LegendI[mem-used]: Total used RAM (MB)
LegendO[mem-used]:
Options[mem-used]: gauge

Target[cpu]: 1.3.6.1.4.1.2021.10.1.3.2&1.3.6.1.4.1.2021.10.1.3.2:community at server * 100  (multiply as 100 because this will return values in the hundreths ie:4.21)
MaxBytes[cpu]: 10000
Title[cpu]: server CPU Load (5 minute average * 100)
YLegend[cpu]: load
ShortLegend[cpu]: load
Legend1[cpu]: CPU Load (x 100)
Legend2[cpu]:
LegendI[cpu]: CPU Load (x 100)
LegendO[cpu]:
PageTop[cpu]: server 5-minute average CPU Load * 100
Options[cpu]: gauge,nopercent,integer


as for NT, good luck....I've tried to no avail, so please let me know if you can do it (although you can get at least eth by installing the snmp service and running cfgmaker against it)


Hope this helps....
