Alert Changes in newest subscription update?

Hello all.  I'm fairly green with Linux as well as Observium.  I stood up the community edition on Centos 3.10.0-957.1.3.el7.x86_64 and found it to be a very useful tool.  Management supported moving to subscription.

I have various alert checkers setup and everything seemed to be very happy and good until updating to revision 9727 on 2/28/2019.  It seemed like Observium started becoming more "sensitive" to things and has generated false positives on devices being down when they actually aren't.

Really, I not remember changes that could affect increase frequency alerts generation (and somehow influence the sensitivity).
Most likely this is due to network delays or problems on the server itself.

You was do recommended server improvements like:
 RRDCached - https://docs.observium.org/rrdcached/
 Overall system tuning - https://docs.observium.org/tuning/
 Poller optimization - https://docs.observium.org/poller/

And show (screenshots) which exactly alert checkers changed their behaviour.

I tried locating release notes on the revision to see if any changes were made to alerting, to no avail.  I just ran another update this morning and we are now on 9775.  I guess what I'm asking is if there were changes to alerting / polling that may require me to tweak my settings.

Thank you in advance for any insight...and this is an absolutely terrific tool.  The subscription price is a steal compared to other commercial packages available that are 10 times the cost and about 100 times less useful.

Very Respectfully,

Hi,

No problems from us, we much prefer 18.04.

Good luck with Ubuntu surviving, though! :)

The state of modern Linux makes me sad.

They say you always become the thing you hate, and Linux has become Windows. Voodoo configuration and black box undocumented behaviours.

Hello,

Is there a docu or install guide for the distributed setup?
I have manually installed the rrd and mysql server - the install script only has the option to install the community, pro stable, pro rolling and unix agent.
How to I install the gui server and pollers properly that they are all getting updated?
Do I have to run the install script on every poller and remove the packages I do not need on them - like mysql server?

thx,
Alex

Hi Alexander,

These are very new features, and the documentation is trailing a little. I think the documentation for the distributed setup on the site is still only partially complete. As is the way when you have to decide between code and documentation! :)

At the moment the script doesn't have an option to install a "partial" install, but a regular one will do fine. You can remove mysql and apache after the install.

When updating the master and slave instances, you only need to do "./discovery.php -u" on the master, since that's where all of the data is held. The rest only need svn up for code updates.

Hi Alex,

Have you ever updated Professional to Enterprise? We've got quite a few years of legacy data in our Professional instance and of course, we'd like to retain all of that during the migration to Enterprise.

Please post again about your progress with distributed Enterprise - that's the next challenge over here.

Many thanks

Darren

Thanks Adam, yeah – noticed the enterprise version and distributed polling is new and highly appreciate that features.
I’ve installed one manually and one with the script – only wanted to make sure I’m not doing anything wrong or messing up something.

We have a datacenter in US, EU and CN where the RRDCache and MySQL instance is running in EU and I want to deploy two or three pollers in every other datacenter.
Anyone using MySQL active/active or Galera cluster or is it recommended to stick with a single MySQL server?

Thanks,
Alex

Hi Darren,

No, it’s a fresh install – I was using the community version for nearly two years and I’m quite happy with it.
Since the community version is running on Wheezy I’m doing a fresh install on Stretch.
