monitoring vsphere 4.1 with icinga / pnp4nagios

Posted: December 1st, 2011 | Author: | Filed under: debian, ibm, infrastructure, it, linux, networking, virtualization | Tags: , , , , , | No Comments »

the first time i build a icinga monitoring for a vsphere environment. before i configured only checks for esxi machines directly. love the check_esx3.pl module from op5.com. some pics from pnp4nagios:

got the system running on a debian squeeze, all packages from the main,nonfree,controb repositories. pnp4nagios is backported. so all packages are covered with security updates and the normal apt super cow power !

vmware vsphere and symantec endpoint / webserver port conflict

Posted: November 16th, 2011 | Author: | Filed under: it, networking, virtualization, windows | Tags: , , , | No Comments »

got an customers w2k8 r2 mgmt machine with symantec endpoint and vmware vsphere. the problem: after installing the endpoint product under vmware vsphere the performance graphs for the vm’s don`t apear and the client crashes immediately(detail: the vmware webservice services crash and cannot restart successfully). cause: both software product got webservers on board, that means port conflicts. the solution: the machine got two nics; one nic for mgmt net, one nic for a production net. i changed in the vmware tomcat config the localhost definitions to the mgmt ip because i saw that the endpoint used the other interface automatically. now the tomcat services for the vsphere installation run on a different interface and there are no more conflicts with the two webserver instances… the better solution is not to install two products with different webservers on one machine – especially under a windows server.

two ssg5`s and a mag2600 arrived for production, will do a classic ipsec vpn setup between the branches and a hopefully funky sslvpn setup … šŸ™‚
