email notifactions

[kevin]

Thanks Marcus, I changed the minimum number of faults to 1 and now I am getting a more realistic representation of the real problems.

[cloudlinux]

It took me almost all of the 14 day free trial period to work out how these notifications worked and their subsequent eMail notices
I agree, there is a complete lack of (easily found) documentation but it is there

The first thing to be aware of is that all the items being monitored are classed as processes; CPU, Memory, IO, and NPROC
The first slightly misleading item is the NPROC

As per my reply #8
The Memory is not the actual memory in RAM, but the number of 4KB pages
This just means you need to remember to either multiply or divide by 4, depending on what you are trying to achieve

However, I had severe problems trying to work out where to find the cause of an account reporting Excessive Account Resources
Once I had all these settings within LVE I then transferred them to LFD, and this resolved the issue
I now receive an hourly eMail from LVE (if an account exceeds a resource) followed by one from LFD explaining the actual cause

Any chance youd be willing to release your modified version to the community Host Provider?

Sure. Here is the code that I am using. It needs to be tweaked a bit to send to the account holders, as for now we have it sent only to admin. But it gives a much better report than the useless one CloudLinux is doing...

Its PHP code, and needs to run via cron with whatever frequency you want.

These notifications are most stupid thing any progeammer ever introduce...I just had server overload with your stupid notifications to resellerss end users...one reseller had 4 accounts with bots and while LVM worked perfektly to limit server resource abuse from users and reseller but than it abuse it it self by sending few thousand emails and mail in queue there was about 10000 emails...what I dont get it how it can send such huge number of emails when it was configure to send notification every 1 hour ...also why I as server owner cant disable sending notifications to resellers users???You should set this feature completly optional since it is completly useless...now I have set "Minimum number of Faults to notify end user" to 1+ nice amount of ziros and if this doesnt work I will remove it completly and maybe even move to Centos .

20 minutes after I empty mail queue ..142 records and 230 already sent ...372 emails for 20 minutes.. https://s25.postimg.org/wur1jkian/Screenshot_32.png

What do you have in settings for notifications? Unless you set it to email once a minute -- I dont see how that could have happened. It is either a bug, or you have set settings to send notifications very often. The defaults are once every 12 hours.
