I had some severe performance problem lately on my dreamhost shared server, and eventually they disabled some of my domains.
At the end of a long discussion with "support" i understood that the problem in not a singel domain, but having too many domains on one user. My bad, i'm still learnig.
So i think i found the solution of the problem, and i ask if i can make some tries asking them to warn me before shutting off my site again. They said that the shutting is automatic and if it happens too often they could force me on a VPS (= expensive) without warn!
I decided to look for a tool to monitor my server and warn me that something bad is happening before DH shut off my site again.
I found zabbix that looked nice, but reading around i saw that it use a lot of memory and it can be installed only on VPSs!!
The question is: is zabbix worth and working on a shared server? or it will suck up all my scarce resouces? Is there any other good alternative for monitoring a shared server?
