We have a few VMax arrays configured using SNMP to send alerts, one  day I received 90% write pending. (see alert string), as you know  symstat only gives WP tracks for each SymDev - so checking the current  WP % is difficult. Anyone knows how to get current WP rate? ( I did -  greping total every minute and divide it by the max wp slots)
