I'm using PRTG to monitor a large selections of servers, mainly for backups (Symantec System Recovery primarily).

I'm testing WMI and SNMP sensors at the moment and can successfully receive the backup job status messages from each of these. However I don't want to rely on jobs reporting failures.

With the IMAP sensor you can set the status to down if it doesn't see a success message. Due to limitations to the number of concurrent connections to the mail server, switching to this doesn't seem possible.

Can "Set status to down if no success in X hours" be set on any other sensors?

Hi Greg,

Sorry, That's not possible. You can only set the sensor to go down after 5 scans with a "down" result and stay in a warning state until then (located in the sensors scanning interval settings).

Aside from that, such a configuration is not really possible :(

That's very disappointing - is there a feature request form somewhere I can add this to?

I can't rely on something that has failed reporting its own failure (been stung in the past with this).

For example if something blocked SNMP messages from reaching the sensor it would still show a happy green sensor no matter what else was happening - a terrible place to be with backups!

As IMAP is the only sensor that can offer this, is there a way of setting it so it only accesses the mailbox once rather than once per sensor? Last time I saw this tested it would just lockout the email account if used with a large number of separate sites. (Exchange 365 limiting connections)

Thanks again, Greg

The mail sensor doesn't have such a feature, it's rather a sensor specific filter that only checks mails that are [n] hours old. You could only work with higher intervals here I guess :/

edit I'll flag the thread as feature request if you don't mind :) If enough people want such a feature (collect mail requests and check them with a single connection), it will probably be considered for future development.

Thanks for your input!

Thank you, it would be good to see if anyone else has similar thoughts.

Admittedly my preference would be to continue to use SNMP but if we can use an Office 365 mailbox for this without it being locked out by the connections, it wouldn't be a bad alternative.

Greg.
