Severity | Determined by Threshold values. See below.
Message | SRDFA cycles now using <NN> percent of the cache available for it.

This is a Threshold event that indicates the percentage of cache that is available for SRDFA use that is actually holding SRDFA Write Pending data.

Unless threshold values are supplied with the registration, the following defaults are used to derive an event severity:

If value is >= 90% — Warning

Otherwise — Info

## Notes

- This is determined by calling SymReplicationGet() and summing the active_cycle_size and inactive_cycle_size values for all active R1 or R2 sessions. The maximum available cache is computed in the usual manner:

    if 	((max_host_throttle == 0) and
     	 (rdfa_max_cache_usage > 0) and
     	 (rdfa_max_cache_usage < 100))
    	max_avail = (max_wr_pend_slots * rdfa_max_cache_usage) / 100
    else
    	max_avail = max_wr_pend_slots

The event value is the sun of the active and inactive cycle sizes expressed as a percentage of this max avail cache size.

- warning: Exercise caution when assigning significance to this event. The fact that an amount of cache is available for SRDFA to use (max_avail above) doesn't mean that it is guaranteed to be available for its use. There are other sources of Write Pending data that can use up this space as well - leaving it unavailable for SRDFA's use.
