Hi Ghandi, do you find something in order to have the uptime information ? i'm going to leave MRTG for CACTI and the only information that is missing is the system uptime.

Thanks

Here's how I monitor the system uptime:
* Create the following script (I call it uptime.sh):

Code: Select all

#!/bin/sh
uptime=`snmpget -Ov -c $1 -v 1 $2 system.sysUpTime.0 | awk '{print $3}'`
case $uptime in
*:*) uptime=0 ;;
*) ;;
esac
echo "$uptime";

* Use the following data and graph templates (exported on cacti 0.8.6c). This is my first time adding a template so I hope I got it all. Your uptime graphs should look like:

Hi,

hi,

thanks for the info, but the last message in this thread is for me, i need this under windows this patch doesn't run in windows..

is there really no commant?

bad

Hi Ghandi,

I had a look at the patch. It won't run on Windows because it calls a Skript using the *nix notation.
If you replace the line

Code: Select all

@$uptime = exec("/home/httpd/html/cacti/scripts/snmp_cisco_uptime.sh " . $hostdata["snmp_community"] . " " . $hostdata["hostname"]);

with something like

Code: Select all

@$uptime = exec("C:\...\uptime.bat " . $hostdata["snmp_community"] . " " . $hostdata["hostname"]);

then it should work on Windows as well.
P.S. I don't know anything about PHP and am not running CACTI on Windows so please handle my advice with care

that's not so easy because there is no patch method for cacti running on windows. But if you found something i'm interested.
thanks

I see ... but in this case you only have to add a few lines. The line numbers can be found in the heading of the patch file - so this should be quite easy to patch manually.
But as I said before, I have no CACTI running on Windows ...

[Ghandi]

what i doesn't understand is, uptime is a snmp query, why its so difficult to add the uptime from a host... ?

is there no host or graph variable for this feature?

greetings

[Thomas]

No, there is no variable for this feature (in this version of CACTI).
I would create a separate graph for uptime (see my above example) - this gives you the needed information with least effort.
BTW: What uptime data do you want to monitor? .iso.org.dod.internet.mgmt.mib-2.system.sysUpTime (.1.3.6.1.2.1.1.3) = "The time since the network management portion of the system was last re-initialized." or .iso.org.dod.internet.mgmt.mib-2.host.hrSystem.hrSystemUptime (.1.3.6.1.2.1.25.1.1) = "The amount of time since this host was last initialized."

P.S. Schöne Grüße vom Bodensee nach Graz

We currently keep uptime in one of our tables. It would not be a major hack to provide it as a GPRINT in the next version.

[Ghandi]

ok, than i will wait for the next version... i have enough time to wait.. but not enough to work on scripts *g*

thanks..

Who I can add this graph (detailed) on my Cacti system using Net-SNMP for Windows?

[Thomas]

SNMPGET returns the following value:

Code: Select all

Timeticks: (43847204) 5 days, 1:47:52.04

My script takes token 3 (with AWK) and checks if it contains a ":". If yes, then uptime is < 1 day and the script returns 0.
If you can create a script (perl?) then it should be possible for windows as well.
I've found the following skript for an UPS:

Code: Select all

#!/usr/bin/perl
#
# Script to convert runtime MIB variable for UPS into minutes

$a=`snmpget -v1 -c public $ARGV[0] .1.3.6.1.4.1.318.1.1.1.2.2.3.0`;
chomp $a;
@b=split(/ /,$a);
@c=split(/:/,$b[4]);
$z = eval($c[0] * 60 + $c[1]),"\n";
print $z;

Please be careful and test all code! I'm running on Linux so my Windows suggestions are all theoretical!
