Display uptime?

[chexhcky]

Any way to get an Uptime display for a host, in a graph preferrably? Looking to get similar to what MRTG provides.

Thanks

Create a script <path_cacti>/scripts/snmpUptime.sh with this:

snmpget -v1 -Cf -c $1 $2 $3 | awk '{ print $5 }'


Create a Data Input Method linking to this script

Input String:
bash <path_cacti>/scripts/snmpUptime.sh <community> <host> <oid>

Output String:
<uptime>


On the Data Template write the OID:
.1.3.6.1.2.1.1.3.0

You guys have to be more descriptive than this...
Please try to assume that other people who aren't familiar with this sytem will be reading it

Is there anyway to print the whole string value as a GPRINT on the graph as opposed to graphing the actual integer value?

You can add a graph with no color. The problem with this is that if the uptime value is larger than the rest of the graphed items, the graph will be wrongly scaled.

I've made a change here to allow the uptime to be displayed in the graph as a comment. It uses a script to do an snmp get on the target device. After applying the patch you can just use |sys_uptime| in your comment and it will replace it with the uptime.

e.g Uptime: |sys_uptime| will print a comment like Uptime: 195 days, 14:04:22.12 on the graph.

You might need to change the path to your cacti scripts directory in the patch before applying it (sorry I couldn't make it cleaner!).

Argh! Forgot to login again!

This is what the uptime on the graph looks like.

Speedster - Your patch applies cleanly to 0.8.4, but for some reason I'm unable to get the uptime onto the graph. I'm using FreeBSD 4.9 and I did check that the OID reported the uptime. I had to edit the patch to get the path to the script correct, and the script is exectutable - so I'm at a loss why it won't work. Any thoughts?

[Guest]

Not sure, I've generated the patch against 0.8.5. At a guess I'd say it's either not entering the text substitution for some reason.

Speedster.

Can you pls let us know how to apply this patch on linux sys.

Thanks

Once you have put the script in the scripts directory and edited the diff file so the paths are correct, run

patch -p0 < /path/to/rrd_php_show_uptime.patch

from your cacti directory

Hi guys,

I've made patch but graphs no longer showing. I get an erro message when I click on "source":

Code: Select all

script name for uptime is snmp_cisco_uptime.sh under script/ directory

Can anyone help me with this?
Thanks in advance

Are you using 0.8.5 or have you upgraded to 0.8.5a? I found when applying the patch to 0.8.5a the text substitution variables had changed since 0.8.5.
