Thold 2.x - Thresholding/Alerting module for cacti 8.6

[rik]

äähhhmm...

no it is not a windows specific problem, because i am working with freebsd in a jailed enviroment and uni_tom has the same problem on his redhat linux.

i had no time to look further to solve this till now.

I'm having a similar problem to the current value showing 0 but mine is not showing anything for the current value at all.

I am using the following:
Windows 2000 Server
cacti 0.8.6f
Plugin Arch 0.6
Thold Plugin 0.2.4

Hey guys I think I have a fix if you have problems with thold showing a 0 or nothing in your Threshold column when you view your thresholds.

I believe the problem has something to do with the way RRDTool reports the last entry time. In the [cacti-root]/lib directory the thold-functions.php file has a function called get_current_value() that uses the an "rrdtool last" call to figure out when the last time the RRA had anything stored in it. But it appears that the actual time of the last record and whats reported by the "rrdtool LAST" command is different. For me it was different by one second. But this second is extremely important because the time reported back by the "rrdtool LAST" is used in the get_current_value() function for thold.

So based on some earlier posts about problems with thold not alarming on thresholds I did my own little "hack" to the thold-fuctions.php file. What I did was this,

Current get_current_value() function code in [cacti-root]/lib/thold-fuctions.php,

Code: Select all

function get_current_value($rra, $ds)

{
        global $config;
        $last_time_entry = rrd_last($rra, "MAX");
        $last_needed = $last_time_entry + 900;

        $result = rrdtool_function_fetch($rra, $last_time_entry, $last_needed);

        $idx = array_search($ds, $result["data_source_names"]);
        return
}

And changed it to,

Code: Select all

function get_current_value($rra, $ds)
{
        global $config;
        $last_time_entry = rrd_last($rra, "MAX");
        $last_time_entry = $last_time_entry - 100;
        $last_needed = $last_time_entry + 900;

        $result = rrdtool_function_fetch($rra, $last_time_entry, $last_needed);

        $idx = array_search($ds, $result["data_source_names"]);
        return
}

Basically I added $last_time_entry = $last_time_entry - 100; after the rrd_last() function call to decrement the last time the RRA had data stored in it by 100 seconds. This seemed to fix my problem.

Hi all.

First thanks for this really good and needed addon.

I would like to know if there is a way to add the threshold to a default template so that it is created at the same time as the graph itself.

Ex: having a threshold for every interface i graph...


I also created a set of templates to graph process monitored by ucd-snmp and netsnmp. One graph per process, with also the error field. It is then easy to graph a single daemon and put a threshold on it.
Just ask if someone neet it.

Cheers

[lgastou]

Hi Prune,

I will be very interested by those templates, So if you could post them on the forum, this could help others people than me too.

Thank you (Merci) for your help
Regards

Laurent

This does seem to help. I still get zeros but now it lists them as not triggered.

I was getting the Undefined offset: 0 on line 37 error. I removed [0] from line 37 in the thold-functions.php file and the error disapeared but I still just get zeros.

I changed:
return round($result["values"][$idx][0]);

To:
return round($result["values"][$idx]);

I know very little about programming. I was just playing with the code to see if the results would change.

Edit:
I can also trigger the alerts by adjusting the high or low threshold levels. So I know that it is getting the correct current setting, it is just not displaying it.

Hi all,

First of all, thanks a lot for Cacti application, and also for Treshold addon.

This is my first post here.

You will find as attachement, treshold addon for cacti 0.8.6g.
This archive is only for cacti 0.8.6g under Unix. I have not tested under Win32.

Also include on this archive treshold-sorting patch.

Installation script is different from the original one.
I have prepare patch file. That give you choice of patching original files, or copying new one.

Have fun !

[cmarsot]

Hi,

I have few questions about treshold addon.

1/ Will it be possible to have treshold configuration during graph creation ?
2/ Will it be possible to have different treshold for specific range of hours ? (example, having a high treshold traffic during days of 20Mbps and a high treshold of 5Mbps during nights)

Have a nice day !

[Hardinxcore]

Hy,

I want to install Thold on my Windows server 2003 machine.

Can anybody tell me how to do that?
Where can I find a manual ore someting?

Cacti 8.6f is already running good.
Thnx in advanced!

Greet, Hardinxcore

I'd like to know this as well. Any ideas on this?

[cjennings_cr]

I have Windows 2000 with cacti 0.8.6g and just downloaded the latest thold for this cacti release.

I manually installed it:

1) Backed up cacti files
2) mysqldump-ed the database
3) mysql cacti < thold.sql
4) created / copied (overwrite) the following files:
...a) {cactibase}\thold\check-thold.php
...b) {cactibase}\thold.php
...c) {cactibase}\listthold.php
...d) {cactibase}\images\tab_thold.gif
...e) {cactibase}\graph_thold.php
...f) {cactibase}\include\config_arrays.php
...g) {cactibase}\include\config_settings.php
...h) {cactibase}\data_sources.php
...i) {cactibase}\graphs_new.php
...j) {cactibase}\lib\functions.php
...k) {cactibase}\include\top_graph_header.php
...l) {cactibase}\include\top_header.php
...m) {cactibase}\lib\thold-functions.php
5) activated the check-thold.php as a scheduled task.

I have seen no errors that pop out at me - but - I don't have the thold data template - so I can't do anything.

Any ideas?

So based on some earlier posts about problems with thold not alarming on thresholds I did my own little "hack" to the thold-fuctions.php file. What I did was this,

Current get_current_value() function code in [cacti-root]/lib/thold-fuctions.php,
Code:
function get_current_value($rra, $ds)

{
        global $config;
        $last_time_entry = rrd_last($rra, "MAX");
        $last_needed = $last_time_entry + 900;

        $result = rrdtool_function_fetch($rra, $last_time_entry, $last_needed);

        $idx = array_search($ds, $result["data_source_names"]);
        return
}


And changed it to,
Code:
function get_current_value($rra, $ds)
{
        global $config;
        $last_time_entry = rrd_last($rra, "MAX");
        $last_time_entry = $last_time_entry - 100;
        $last_needed = $last_time_entry + 900;

        $result = rrdtool_function_fetch($rra, $last_time_entry, $last_needed);

        $idx = array_search($ds, $result["data_source_names"]);
        return
}

Utilizing this solution solved the problem for me. Windows 2003, Cacti-0.8.6f, RRDtool 1.2.10.

My value ended up working at -200. I believe this value has to do with how long it takes for your poller to actually work. Mine takes about 2 minutes, 30 seconds so -200 worked for me great. Play with this value until it comes out correctly.
