Thresholding / Alerting Plugin - Official Q/A Thread

[akaevgen]

Hi. Help me anyone!
I try to use baseline threshold and THOLD plugin move only to warning state, not alert.
In my test the threshold in permanent warning state. What i must do? Thanks.

In investigating, it is pulling the thresholdname from the data_template_data table and using the cache name which is the data source name and not pulling the threshold name from the thold_data. This makes it hard to identify which threshold is sending the notification without looking at the threshold list to see which one has been triggered.

I have found that if I go to the data source option and add the extra information into that name it reports as I expect but it would be more convenient if the thresholdname parameter actually used the name from the threshold setup page.

As a workaround, try to modify 'plugins/thold/thold_functions.php'.
(I'm using thold-0.4.4-41, but not fully tested)

At line 527:

$thold_alert_text = str_replace('<THRESHOLDNAME>', $desc, $thold_alert_text);
to
$thold_alert_text = str_replace('<THRESHOLDNAME>', $item['name'], $thold_alert_text);

At line 561, 592, 631, 649, 694, 622:

$subject = $desc . ($thold_show_datasource ? " [$name]" : '') . ...
to
$subject = $item['name'] . ...

* If you want to know particular datasource name which was triggered, leave "($thold_show_datasource ...)".

Thanks worked out great

It seems that baseline monitoring doesn't change to Alarm state.

Probably it shows one of them:
- Warning = Breached and Triggered
- Notice = Breached, but not yet reached "Trigger Count"
- Ok = Normal
- and Disabled

Thx u

'Warning' is actually 'Baseline Alarm'. I've corrected in SVN. We will be releasing 0.4.4 officially shortly.

Hi (sorry for my bad english ),

I've just installing Thold plugin for cacti and I was having a problem:

When the thold plugin is installed : settings.php show me "Fatal error: Call to undefined function define_syslog_variables() in [...]/cacti/plugins/thold/includes/settings.php on line 132"

the function "define_syslog_variables" seems to be obsolete (and deleted in php 5.4) see: http://www.php.net/manual/en/function.d ... iables.php

I don't know if you can update the plugin in order to fix the problem? (I've just comment the line and it seems to work perfectly)

Hi together,

first - great plugin.

For me nearly everything works fine. I have done many tests. Finally I found one problem but I do not see a solution.

I have created different "Threshold Templates", e.g.

+ Cisco Router - 5 Minute CPU [5min_cpu]
+ Cisco Router - SAA [lossSD]

The problem is that when I try to "Apply Thresholds" under the "devices" section, it works with "Cisco Router - 5 Minute CPU [5min_cpu]", but it does not work with "Cisco Router - SAA [lossSD]". I do not get an error message nor do I see an indicatioin why it does not work.

Strange is that it is possible to create the "Cisco Router - SAA [lossSD] threshold" manually using "Threshold => Add". It is also listed afterwards when I go to the Threshold "Top Tab". Strange is that the newly created threshold shows a 0 ID when checking the graph icon: "https://x.x.x.x/CACTI/graph.php?local_graph_id=0&rra_id=all".

This only happens with the SAA:

Would be great if somebody has got an idea.

Installed... yet... a question... it says: "Data Source Item [traffic_in] - Current value: [38128.5867]".

What does this actually mean? I want to get a mail when my switch (port 24) is doing 30mbit+ for more than 2 hours...

Yet I have no idea how to set up the treshhold and what "38128.5867" means.

================

Hi!

I had the same problem and asked myself what number is used. But after checking the XML i remembered that traffic is gathered in Bytes and not Bits.

This means:

The interface statistics are done in Bytes. This means that you have to translate into Bits.

30 Mbps = 30.000.000 Bps

30.000.000 / 8 = 3750000

So 3750000 is the value you have to enter into the tool as high threshold.

Hope, this helped.

Hi together,

I have the following problem.

For some reason Cisco ASAs report the wrong CPU value sometimes.

Example:

DEVICENAME DEVICENAME - 5 Minute CPU [asa5min_cpu] 2013-03-17 05:17:03 80 4294925 Alarm High/Low ALERT: DEVICENAME - 5 Minute CPU [asa5min_cpu] [asa5min_cpu] went above threshold of 80 with 4294925

When taking a look at the cacti graphs aftwarwards a gap is shown because cacti only graphs values up to "100".

I assume that "Threshold" gets the data before it goes to the graphs.

Do you have an idea how this problem could be solved?

Maybe it is possible to ignore values above 100 somehow?

Hi, did you ever figure this out? I am having the same exact situation here.

New Cacti user here, trying to install this Thold plugin, but finding all of the cactiusers.org links redirecting to blog.cactiusers.org, which doesn't seem to have any of the info I need...

I just need the instructions for installing the Plugin Architecture, the Settings Plugin, and the Thold plugin, but all of this data was apparently only stored in the Cactiusers Wiki, which apparently no longer exists! Help!

EDIT: Okay, I was able to get my hands on the documentation through the Wayback Machine, but I've hit a brick wall on the plugin architecture installation. I am going to try to update to a backport of 0.8.8a (I'm running Ubuntu Precise 12.04) and I'll post to the Plugin Architecture forum if I need further help. Sorry if this was the wrong place for this-- you can return to your regularly scheduled program now. Thanks!

Regards,
Jon Heese

Does this not work with Cacti 0.8.7e?
Thats what I have, plus Settings 0.71 and thold 0.5.

I want to create a thold for some ports for our isp's if they go maxed out to detect ddos attempts.
However when I fill out the information and click save, it says record updated and then all the values disappear. Then if I click threshholds on the left side, it shows No rows found / No Thresholds. So its not taking.
