Performance tuning recommendations for event and impact management
The following tables list parameter names, file names, descriptions, and recommended values to tune a Infrastructure Management environment that performs both event management and impact management.
Heap tuning parameter
Parameter name | File name | Description | Recommended value |
|---|---|---|---|
| Pnjserver.conf | MaxHeap, in MB, allocated to JServer process | Small: 2048 |
| Pnagent.conf | MaxHeap, in MB, allocated for Integration Service | Small: 512 |
Cell tuning parameters
Parameter name | File name | Description | Recommended value | Tested value |
|---|---|---|---|---|
| Mcell.conf | The number of events retained in repository | Set higher for a higher event rate. | 400 K |
| Mcell.conf | The minimum time before CLOSED events are removed from the repository. If no scale factor (s, m, d, w) is specified, the numeric value is seconds. | Set lower if event rate is high. | 1d |
| Mcell.conf | The maximum size of a transaction file before it is transformed into a new saved state when the state builder runs again. If no scale factor (k, K, M, G) is specified, the numeric value is kilobytes. | Set higher for a higher event rate to avoid frequent state builder runs. | 50M |
Additional tuning parameters
Parameter name | File name | Description | Recommended value |
|---|---|---|---|
| pronet.conf | Duration, in milliseconds, after which the Integration Service status cache is refreshed on the agent controller | Small: 180000 |
| pronet.conf | Frequency, in milliseconds, at which the agent writes a KEEPALIVE message to the agent controller | Small: 50000 |
| pronet.conf | Number of retries the agent controller makes before marking an Integration Service UNREACHABLE | Small: 4 |
| pronet.conf | Maximum number of threads permitted for the Integration Service JVM (buffer 10% for the instances to be discovered) | Small: 25000 |
| pronet.conf | Polling interval, in milliseconds, for the agent controller to poll each Integration Service for status | Small: 180000 |
| pronet.conf | Maximum number of threads permitted for the event cache module in JServer process | Small: 20 |
| pronet.conf | Maximum number of threads permitted for the database event insert/update module in JServer process | Small: 20 |
| pronet.conf | Maximum number of connections permitted in the JServer connection pool | Small: 20 |
| smmgr.conf | Maximum time for the cell to reply success or failure of the upload. For large models, BMC recommends using a larger value | Small: 900 |
