As a security administrator, you monitor cache size to balance storage needs and performance and to be aware of performance impacts from the cache being emptied too frequently. Your external security manager (ESM) stores recently-accessed security data in the cache to improve performance. The ESM flushes the cache when cache size reaches the defined maximum. After the cache is flushed, performance slows while the cache rebuilds.
Therefore, you monitor cache size to ensure the cache is not flushed too often. You also monitor cache size to ensure that the cache is not too large, thereby wasting critical storage. You configure and maintain proper cache size by monitoring cache size over time.
You can use CA Chorus for Security and Compliance Management to visually monitor cache size in any dashboard from the Metrics panel. You can also perform more detailed monitoring when you configure alert thresholds, and add a cache to your dashboard.
