Obsolete :

like suggesting by torstentfk, i think that Cacti must checks the uptime of
devices, and signal if the device has rebooted.

so i have done this plugin, using thold and working with cactid


1. decompress plugin in <cacti base dir>\plugins\uptime

2. install plugin (see plugin architecture documentation)

3. optionnaly, use patched host.php (ONLY with Plugin Architecture 0.9)
(this file is only here to add fonctionnality to Uptime and Monitor plugins)

TODO :
i don't need them but all features i want to include are already in thold :
- weekend or hours exception (because my windows servers are rebooted the weekend...)
- global or extra notify...

NB :
for hours exception in thold, see this :

gilles,

Great plugin!
I have just a little suggestion...
Change the line:

Code: Select all

print round(($q_row["uptime"])/8640000, 1) . "d " . (($q_row["uptime"])%8640000)/360000) . "h";

to:

Code: Select all

$days=floor(($q_row["uptime"]/8640000));
$hours=floor((($q_row["uptime"]%8640000)/360000));
$minutes=floor(((($q_row["uptime"]%8640000)%360000)/6000));
print $days . "d " . $hours . "h " . $minutes ."m";

Thanks in advance!
(...and sorry for my poor English!)

gilles,

I just received +1300 e-mails with the subject "Reboot detected of host:..." from all my hosts that are "Disabled" or "Down"!!!
There is any way to correct this?!
I think that the Uptime plugin should send e-amil only when a reboot is detected in a host, and not when a host is down or when it is disabled!

Thanks in advance!

I thank you for your message.

I think that the Uptime plugin should send e-amil only when a reboot is detected in a host, and not when a host is down or when it is disabled!

I have updated the plugin.

Now, it check if host is down or disabled.

I have also resolve a bug for the checkbox "check uptime".

I have updated too "host.php".

I'm going to see a method to clean the table "uptime" when you delete a host.

Hi,

I am happy that my suggestion is now ready for a plugin.
I change my installation and found some issues:
- the sorting o fthe uptime is not correct.
Please use BIGINT as the type of uptime not strings.
- the sort for Uptime-ASC/DESC does not remove other sorting. everytime i click on Uptime (for resorting) I get different views.
- posibility for mass-change to enable all hosts to check uptime.
(I made this via phpmyadmin)

...Works great!

Done.

Uptime plugin has been updated.

I have installed the uptime plugin and it is working as I see the uptime on the devices page, but when I go to the "Uptime" tab, none of the systems that I have chosen to be monitored are listed? I noticed in your images that you have an option to monitor uptime in the drop down menu that I do not have (I have the checkbox on the individual devices page). Am I missing a step somewhere or would this be a part of the patched host file that is included? thanks.

***EDIT*** Sorry, just used the patched host.php file and it does add the uptime option to the drop down menu and also just realized that the "Uptime" tab lists last reboot and since none of my systems have been rebooted, probably explains why there is no data there.

Its not showing any thing on the devices page....do i need to install the .sql file with the command mysql -p cacti < uptime.sql.....provided in the rar file....its showing N/A....but i have snmp enabled on all the devices....

Hi,

the reboot-monitor alert if the device is more than 497 days up, Mail:
"Host : xxxxx, old uptime was : 4294951006 (497.1d), new is : 13353 (0d)"
(The snmp-variable only stores 32bit of ticks=497 days)

It would be nice, if the plugin checks the old uptime and if it detects a reboot it should check also the uptime beeing between 497 and 498 days. If it is so there should be no alarm.

Great plugin work !!

This has been working very well in our case, I would like to offer a feature suggestion. Our network has many technicians for many different circuts. We monitor links for other companies as well.. I would like to be able to send individual notices for each device to only certain technicians. For example, reboots should notify:

device1 : tech1@host.com, admin@network.com
device2 : tech2@othercompany.com, admin@othercompany.com

Is that something that can be coded into the plugin?

Thanks !!

Found time to change it: file "check-uptime"
Insert before last if-Statement: if (($old_uptime<4294937286) || ($old_uptime>4294967297)) {
insert after befor last 3rd } another }to close the new if-statement

Also changed the thold_mail - function call:
thold_mail($global_alert_address, '', 'Reboot detected at' . $reboot_date . ' of host : ' . $q_row........

Hello developer,

found a bug for computing the uptime at host.php. The floor function could not read BIGINT or it does not run with very big numbers.
I changed this:

Code: Select all

# diff host.new  host.php
835,836c835
<       $sql_where =" ON host.id=uptime.id ";
<     $sql_where .= "where (host.hostname like '%%" . $_REQUEST["filter"] . "%%' OR host.description like '%%" . $_REQUEST["filter"] . "%%')";
---
>     $sql_where = "where (host.hostname like '%%" . $_REQUEST["filter"] . "%%' OR host.description like '%%" . $_REQUEST["filter"] . "%%')";
852a852
> 
857c857
<               from host LEFT JOIN uptime
---
>               from host
870,872c870,871
<               host.availability,
<                 uptime.uptime
<               FROM host LEFT JOIN uptime
---
>               host.availability
>               FROM host
909c908
<               "avg_time" => array("Average (ms)", "DESC"),
---
>               "avg_time" => array("Average (ms>", "DESC"),
940,942c939,942
<     $days=floor($q_row["uptime"]/8640000); $r=$q_row["uptime"]-$days*8640000;
<     $hours=floor(  $r/360000 );  $r=$q_row["uptime"]-$days*8640000-$hours*360000;
<     $minutes=floor($r/6000); 
---
> 
>     $days=floor(($q_row["uptime"]/8640000)); 
>     $hours=floor((($q_row["uptime"]%8640000)/360000)); 
>     $hours=floor((($q_row["uptime"]%8640000)/360000)); 
>     $minutes=floor(((($q_row["uptime"]%8640000)%360000)/6000)); 

I use the host.php version where I can sort the columns by clicking in the headers. Please check this and incoorperate it in the future versions.

This looks like an awesome patch. I am having troubles getting it to install. I have decompressed the files but am not sure how to install it. Can someone help?

Thanks,
