Does anyone know what tools?

Don't use them so I didn't think of that.

In the Integrated Management Logs on managed systems, you cannot set the reported events to "Mark Item Repaired", or "Clear all IML Entries" if you do not use an SNMP-community with READ/WRITE rights.<BR />Most default server installations only use an SNMP-community "public" with READ ONLY rights.<BR /><BR />The Integrated Management Log can be accessed via the System Management Homepage.<BR />Sometimes HPSIM reports a hardware status Orange when specific events are logged in the IML (like BlueScreens etc.).

When using 'Configure or Repair Settings,' HP SIM will define a random string for each system to eastablish a write community string at the target system. The string is used for intra-agent communications and is never transmitted over the wire (i.e. can't be sniffed on the network).<BR /><BR />All 'write' operations that HP SIM does over the wire are complete via HTTPS.<BR /><BR />Intra-agent communications include:<BR /><BR />- setting disk thresholds<BR />- clearing the IML<BR />- changing agent settings through the SMH or from HP SIM<BR />- VCA updates Thu, 27 Oct 2005 09:35:19 GMT https://community.hpe.com/t5/server-management-systems/what-uses-the-snmp-write-community-string-in-sim/m-p/3657513#M15805 David Claypool 2005-10-27T09:35:19Z https://community.hpe.com/t5/server-management-systems/what-uses-the-snmp-write-community-string-in-sim/m-p/3657514#M15806 Thanks Claypool that make sense.

(The system where we do digital signing of software is not even connected to a network because of security restrictions.) Everyone needs to make a decision about the tradeoff between security and the amount of management they want to/need to use.
