Graph template for SNMPv2-MIB - sysUpTime

Guest

Hi

I created and exported a template to show uptime graphs.

Be warned that this template includes the dependencies, so be careful not to overwrite your existing implementation with this template (backup your Cacti first).

The data template uses the "SNMPv2-MIB::sysUpTime.0" / ".1.3.6.1.2.1.1.3.0" OID.

There is also a "HOST-RESOURCES-MIB::hrSystemUptime.0" / ".1.3.6.1.2.1.25.1.1.0" OID which could do the same thing, should the other OID not be available to you. Simply modify the data template accordingly.

Unfortunately, these graphs will not show uptime of a host as a percentage, which is a bit more complicated.

Have fun!

Okay, SNMPv2-MIB::sysUpTime is only for the SNMP daemon uptime, which isn't the host uptime. Instead, use HOST-RESOURCES-MIB::hrSystemUptime as you had mentioned.

Here are comments from the MIBs;

SNMPv2-MIB
sysUpTime OBJECT-TYPE
SYNTAX TimeTicks
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The time (in hundredths of a second) since the
network management portion of the system was last
re-initialized."
::= { system 3 }

--

HOST-RESOURCES-MIB
hrSystemUptime OBJECT-TYPE
SYNTAX TimeTicks
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The amount of time since this host was last
initialized. Note that this is different from
sysUpTime in the SNMPv2-MIB [RFC1907] because
sysUpTime is the uptime of the network management
portion of the system."
::= { hrSystem 1 }

Attached is an updated host template with the dependencies.

the uptime returned by net-snmp is the uptime of the daemon, not the uptime of the server

We're using a recently compiled version of net-snmp 5.3.1 on RHEL 4 (Centos).

Anybody care to explain why hrsystemuptime doesn't respond on these hosts. Surely it's not something you'd have to compile support into net-snmp for! Sounds like it should be something always available.

Even our Windows servers respond to .1.3.6.1.2.1.1.3.0.
