Hi ,
I have also same issue with performance of availability report . when i generate availability report then the avail.cfg process takes 90-100% CPU and the result comes to me after 10-15 minutes. I have approximate 5K Hosts and 32K services . And my system configuration is 32GB RAM with 1TB HDD and 16 core cpu with threading . kindly help me to overcome from this .

32K Services is a lot. I suspect you'll need to do some process off-loading. You should take a look at https://assets.nagios.com/downloads/nag ... ios_XI.pdf

There are simpler "solutions" at https://assets.nagios.com/downloads/nag ... ios-XI.pdf, but whether they actually solve your issue will depend on a variety of factors. I'm guessing that 1TB is not a SSD?

Hi,
My Database server are on different machine and i am using 6 Mod_gearman worker to handle the services and we are using 1TB SAS hard disk . So kindly suggest me how to over come from this situation .

Can you PM me your profile? Admin > System Config > System Profile (click "Show Profile" in XI 5 onwards). Thanks!

There aren't a ton of performance improvements in 5.3.x, but there are some. I would suggest giving the upgrade a try before we move on. Instructions are at https://assets.nagios.com/downloads/nag ... nstall.pdf

5.3.x now has an offline installer if that would be useful: http://repo.nagios.com/

Please let us know if it does not improve the situation.
