Foglight-related issues
|
Problem: A Validate Win connection failure occurs. If the Win32_PerfRawData_PerfOS_Processor class is invalid, any queries from it will fail. This is used in the OS connections validation. | |
|
Problem: When the FMS (Foglight Management Server) and FglAM (Foglight Agent Manager) are installed on different time zones, the timestamps in the topology are not accurate. The difference from the real timestamp is: | |
|
Workaround: Use the relevant tab in the Databases dashboard (ASM, CRS, or Exadata) to delete the nodes. | |
|
The 'Agent configuration failed' error prompts by chance when trying to monitor an Oracle instance. | |
|
Workaround: Disable the newer cartridge and enable it again, thereby overriding the settings of the older cartridge. | |
|
An error log showed in FMS log for loading heatmap component in FMS version before 5.9.3. | |

Anti-virus software may negatively impact the CPU and system performance of machines running Foglight. To reduce resource consumption, it is highly recommended to exclude the relevant directory, processes, and executables from being scanned by the anti-virus software. For detailed information, refer to the “Configuring anti-virus exclusion settings” in Installing Foglight on Windows with an Embedded PostgreSQL Database. |
