Exemption Time

Richter · Post by **Richter** » Fri Jun 12, 2009 1:04 pm

Thold is a great Plug-in, it is working perfectly for me!

One thing I would like to try and figure out is if there is a way to create an exception time, similiar to the weekend exemption, where from 8pm - 5am it would ignore triggers. We do backups accross the WAN overnight and are getting several alerts overnight, which we could do without.

I sure would love to have this feature in thold too. Wouldn't mind giving a hand if I can help.

Has any progress been done on this? If not, then I'm going to scratch this itch of mine and submit a patch back to you guys.

Work it over and send it upstream. If it's good, it in.

I've been toying with this (and learning how cacti/thold code works). It's working but need some clean up. Currently only one exemption can be set per template, you can toggle it on/off, select one or many day of the week and choose a start/stop hour.

Things I'd like to add :
More precise time support (ie minutes not just hour). Rather easy to do, I just kept it simple for now.

Multiple exemption per template. Can this be done? I'm thinking something along the line of multiple Data Source in the Data Templates.

Adding a thold Exemption State. Right now, when an exemption is in effect there is no obvious way to know this. What would be better, adding an exempt state? Or just flag it disabled?

What's the best way to send it to you and get some feedback on the code?

It's getting in good shape, tested different scenario on my cacti server. Works rather well.

Hi, I really need this. We have tons of backups running in the evening casuing a lot of alerts. All I can do for now is to try to remember to manually disable/enable alerts every day. Is this patch any closer?

Hi, I'm still testing/debuging this. So far so good. Since SVN is in flux lately I did my patch with thold 0.4.1 (including a few other patches here and there that have been included in SVN).

I can upload a proper patch today if you want to test it.

Here is the patch.

First you have to upgrade the database with exemption.sql. Then run the patch (I made it against a clean 0.4.1). Do a dry-run first. If everything works, you will see that the Weekend exempt is gone on the threshold and templates (but not the Global one, this one still works the same...in fact it is the same). You now have a checkbox to enable the exemption, a multiple choice dropbox and a start/stop time. You can modify it at the template level and at threshold level. Beware when an exemption works overnight.

Example : you have a backup running from 8PM to 2AM starting on monday. You must select monday and tuesday, start at 20h and stop at 2h.

Comments? Questions? Idea on how to improve?

Darkman,
Thanks for the quick reply.
The patch went well, I can see the changes, but I can not figure out how I would set it to exempt Mon to Friday, 8pm to 8am the next day, but then exepmt the weekend from Friday 8pm to Monday morning 8am. In other words, only alert mon to fri 8am to 8pm.

...hope I am not missing the point here.

Ah, I think I was missing the point...
So, in the threshold template I select Monday to Saturday then select the start at 20 and end at 08, which will apply to each day following through to the next, then use the weekend exemption on the global setting.

Excellent work, thank you, Just got this on a test VB at the moment. I will give it a couple of days then wack on the live box.

Yep, that should work the way you want.

Oops, found a possible logic issue. It's the same code but reordered the global check. Made a quick patch for you, just patch over your current test with this one. Also uploaded a new version.

Please open a bug report here: http://bugs.cacti.net and attache your patch and some information on design to cut down the time that the Dev's have to spend reviewing the patch.
