Monitoring instances - SNMP?

Hello, we are a small company in Germany having several geographically dispersed servers running Oracle8 and Oracle8i databases.

The question is, how can one effectively monitor and administer ten Oracle instances? We would like to have e-mail and cell-phone notification about critical events, like e.g. diskspace running out, or a tablespace not having enough space for the next extent. We would also like to have actions defined per critical event, e.g. "ALTER TABLESPACE xxx ADD DATAFILE..." and similar.

We have heard about SNMP, yes, but what's the best way to approach it? Out budget is limited. Also, we access all our databases from a central office by means of (slow!) modems and ISDN connections.

Would MRTG be a right approach? Received on Fri Nov 08 2002 - 04:01:26 CST
