<html> <head> <style></style> </head> <body class='hmmessage'> Thank you for your reply, I would like to give you some detail of our monitoring environment. I configure nagnios on an Virtual Machine based on 2x4Core CPU, 24G Memory physical machine, which runs 4 VMs. Service quantity is 3814 and host quantity is 406. The service check latency is unstable, always changed. Does any configuration error cause that problem? or Virtual Machine capacity result it?<BR>Thanks a lot.<BR> <BR> <BR> <TABLE cellSpacing=4 border=0> <TBODY> <TR> <TD class=perfTitle> <A

server's capacity is about 3000 items. For example, 1000 hosts are defined on nagios servers, and every host offer 3 services monitoring, so total 3000 items are on one nagios server. If item quantity is beyond 3000, nagios performance will dramatically decline. Could someone give me the offical quantity about nagios capacity? thanks a lot.<BR>> <BR>> <BR>> There's nothing official or even unof ficial as there are too many variable involved. Some of them are the type of hardware you're running it on, the types of checks you are doing, the plugins you use and how frequently you check. There's no formula for determining max capacity. It's an art more than a science. The best you can expect is reports about what others have been able to do. It's been discussed before here but it can be difficult to search for...<BR>> <BR>> 3000 is conservative and an easy number on modern hardware with mixed checks running every 5 minutes. I have non-dedicated machines doing that easily on older hardware. I expect that I can easily double, triple or more those checks. There are people who have reported running 10,000+ checks on a single machine (or even more than that).<BR>> <BR>> --<B R>> Marc<BR>> <BR>> <BR>> ------------------------------------------------------------------------------<BR>> Throughout its 18-year history, RSA Conference consistently attracts the<BR>> world's best and brightest in the field, creating opportunities for Conference<BR>> attendees to learn about information security's most important issues through<BR>> interactions with peers, luminaries and emerging and established companies.<BR>> http://p.sf.net/sfu/rsaconf-dev2dev<BR>> _______________________________________________<BR>> Nagios-users mailing list<BR>> Nagios-users@lists.sourceforge.net<BR>> https://lists.sourceforge.net/lists/listinfo/nagios-users<BR>> ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. <BR> > ::: Messages without supporting info will risk being sent to /dev/null<BR> <br /><hr />Windows Live: Keep your friends up to date <a href='http://www.microsoft.com/middleeast/windows/windowslive/see-it-in-action/social-network-basics.aspx?ocid=PID23461::T:WLMTAGL:ON:WL:en-xm:SI_SB_1:092010' target='_new'>with what you do online.</a></body> </html>
