- Yes we do use caretaker
- We started using Caretaker since it's public appearance (and replaced
our own TYPO3-specific-monitoring tool with Caretaker)
- We're currently monitoring roughly 50 T3-instances on roughly 20 Servers.
- Purpose-1: EXT-Security
A: "There's a new Security-Announcement about EXT-123. Which instances
affected and have to be updated/graded?" - "Who knows which instance is
running EXT ABC in version 123?"
B: "Our Caretaker will tell you."
A: "OK, so we have to updated/grade the red-ones" ;-)
- Purpose-2: Webbased Report for Problem-Analysis
Given: In addition to Nagios with email & SMS alerts for basic PING &
HTTP(startpage)-Checks & Alerts, Caretaker is also configured with PING,
HTTP-checks on multiple T3-Instance-Domains and more than one URL per
Domain & Tests with meaningful Expect-Values"
CLIENT: "Our Website is broken - What's Up?"
WE: "It's not. (Caretaker tells us its still reachable but very slow)
however: Caretaker's history of the last few month tells us that this
problem is occurring every day between 12h and 13h, so you/we have
investigate in this direction."
- Purpose-3: T3-Version Updates & EXT Overview
We've written a small JasperReport, which queries the Caretaker-DB for
T3-Versions & EXT-Versions, which we can consult in order to decide
which T3-Instance to update.
- Purpose-4: Performance-Tuning Documentation
Actually we've used Caretaker's history-graphing for http-requests on
special pages even for documenting the benefit of performance-tuning
hth, regards georg
