Hi Mitchell,
When you say "monitor", what exactly do you mean? The definition of a
"Monitoring" tool (in my eyes at least) is a tool that will sit and monitor
your database, and tell you when a problem could be, or is, imminent (via
background processes and alerts).
The list that you specify, whilst all good tools, are not (exactly)
"monitors". Quest's Spotlight is more of a "diagnostics" tool, granted it
has a lot of "monitoring" features, but it is essentially a SQL*Net/Net 8
based client, that has to be open for "monitoring" to occur, and more to the
point, you have to be looking at the screen to notice any "problems". Quests
true "monitoring" tool is I/Watch (or Foglight, depending..).
PocketDBA, again, is not a monitor (we are Expand Beyond's UK distributor).
It is more of a diagnostics tool aimed at the "mobile" market. It has no
mechanism to get an alert or to you the DBA, though it DOES allow you to get
to the bottom of problems very quickly, once you have received an alert
however! ;)
I honestly couldn't comment on Oracle Performance Monitor, having not tried
it.
There are other tools available on the market though. Here's a list of those
that I would class as having "monitors":
Precise (www.precisesoft.com)
Quest (www.quest.com)
BMC (www.bmc.com)
Embarcadero (www.embarcardero.com) - I'm not entirely sure whether
Performance Centre has alerting yet.
Bradmark (www.bradmark.com) and therefore (www.cool-tools.co.uk as well :D)
Oracle (who needs a URL)
There are a number of others out there in the market, with tools such as
"Big Brother" (now taken over by Quest I think) "orasnap", "mamba" etc. .
The ones listed above however, are those that I would list as the market
leaders.
<shameless plug>
We sell Bradmark's offering (NORAD) along with PocketDBA, to allow NORAD
alerts to be sent to a mobile phone (as well as email, pager, SNMP_TRAPS
etc.), and "actioned" straight away with PocketDBA.
</shameless plug>
Remember, often the main driving force for monitors is to ease the DBAs work
load, by giving the day to day monitoring tasks to a tool to handle. If you
need to be watching a screen - this defeats the object! :)
