Issue/Introduction

We tried increasing bulk size to 1000, however it gets reset to 1 as shown when we open hub probe for verification, due to which alerts are getting queued up and getting cleared at only 1 at a time.

Environment

Release : 20.3, 20.4.x

Component : UIM - HUB

Cause

- hub ATTACH queue does not need bulk_size set

Resolution

1. Set hub.cfg parms to:

postroute_passive_timeout = 400
postroute_reply_timeout = 300
hub_request_timeout = 240

Hub bulk size is always set by/on the GET side.

It doesn't matter what you set the bulk_size to on the ATTACH side queue.

2. Check to make sure the GET side of the queue in question is not set to "default"

3. Set the GET side of the given queue to 500.

Tested this with hub v9.31.

Configuring or reconfiguring this ATTACH queue in hub 9.31 via the hub GUI Queues Tab, it remains at a bulk_size of 1000 when I look at the hub.cfg or the Status window.

If a bulk_size of 500 is working as mentioned, but nothing higher, its possible its due to network latency.
