If delta math (as described above) is not causing the negative values, there may be a 64-bit counter that up.time Uptime Infrastructure Monitor is interpreting as a 32-bit counter. In this scenario, any value represented by a figure over 32 bits would automatically roll over to a negative number as a result of Java integer handling.
To help isolate the issue, please contact uptime IDERA Support and supply the following information:
- Architecture of Monitoring Station platform (32-bit or 64-bit).
- Operating System version (32-bit or 64-bit).
- Which specific metrics are displaying negative values?
- Are values being collected from an up.time an Uptime Infrastructure Monitor agent or via WMI?
