Os_mon Release Notes

Os_mon 1.3.7

Fixed Errors and Malfunctions

• UNIX:disksup:get_disk_data() did occasionally fail to return any data about disk usage. Alarms about almost full disks would also not be generated. This has been corrected.

Os_mon 1.3.4

Fixed Errors and Malfunctions

• Changed MAX-ACCESS for diskDescr in OTP-OS-MON-MIB from not-accessible to read-only.
  Own Id: OTP-2693

Os_mon 1.3.3

Fixed Errors and Malfunctions

• Failover of a loaded MIB did not work. When a MIB was loaded on one node and that node crashed, the failover of the MIB to a new node did not work.
  Own Id: OTP-2200
  Aux Id: seq 651, HA75679

Improvements and New Features

• Events in the Windows NT event log can be imported into erlang with the generic module nteventlog.

  Aux Id: seq 651, HA75679

Os_mon 1.3.1

Fixed Errors and Malfunctions

• Failover/takeover of the SNMP agent administering the MIB did not work, since the old implementation tried to delete a Mnesia table on a node which was not up and running (which always is the case at failover). Now the SNMP related Mnesia table is defined to have the local_content property.
