I presently have nagios set up in a guest on a temporary host. We will soon be moving everything to a single 'monster' machine with a backup machine for fail-over. The reason for this background is this:
1. Can I somehow set things up so a guest can execute a pre-defined command script on the host? This would allow nagios to do things like re-start a guest if it is not responding. 2. Alternatively I could run nagios on the host. What would be any performance impact on the guests if I were to do this? It would check approximately 100 customer routers and maybe 3 other machines. This would be the extent of any network resources used, the rest of the checks would be done to the guests ( about 70 checks to do locally) and the fail-over machine. I suspect option 2 is my best way but it would still be nice to know if option 1 could be done. :) I understand the need to keep the host as 'clean' as possible, but in real world situations, I would assume no performance impact or at least minimal if the host runs low resource services such as ntpd, private sshd etc. I am wondering where nagios would fall in the low-impact definitions? Although it has a lot of work to do, it appears to use very few resources. -- Chuck _______________________________________________ Vserver mailing list [email protected] http://list.linux-vserver.org/mailman/listinfo/vserver
