Issue/Introduction

After restarting HUB, alerts are not getting populated on IM alarm console.  In IM message view we are getting request time out warning. Request (get_info) has timed out (timeout interval: 10 sec)  -  03/18/20  13:11:53  -  Warning. nas GUI and alarm views are very slow to respond.

Environment

Release : 8.51
Component : UIM - HUB
nas v9.06HF6

Resolution

Deactivated nas.

Renamed the database.db and transactionlog.db

Dropped/Reset the nas tables:

DROP TABLE NAS_VERSION
DROP TABLE NAS_ALARMS
DROP TABLE NAS_TRANSACTION_SUMMARY
DROP TABLE NAS_TRANSACTION_LOG
DROP TABLE NAS_NOTES
DROP TABLE NAS_ALARM_NOTE
DROP TABLE NAS_CS_STATE_MONITOR

Reorganized the nas tables via Rt-click in the Status Tab of the nas.

Adjusted the hub timeout settings:

postroute_interval = 120
postroute_reply_timeout = 300
postroute_passive_timeout = 180
hub_request_timeout = 120
tunnel_hang_timeout = 300
tunnel_hang_retries = 3

Deactivated unnecessary probes on the Primary hub to free up subscribers on the hub and optimize resource usage.

Made recommendation to increase RAM by 8 GB since the machine is already at 80%. Consult with your vmware admin if they think its advisable based on cpu usage history to add 2 more virtual processors.

IM, alarm counts, and overall Hub, nas and IM responsiveness increased significantly.
