Yes there is. The way I do it is I have a SQL Agent job post tracer tokens at a regular interval to the publishers and then monitor their progress from the distributor (where their history is stored). I created a view in the distribution database that helps with that.
USE [distribution]
GO
IF EXISTS (SELECT * FROM sys.views WHERE object_id = OBJECT_ID(N'[dbo].[tokens]'))
DROP VIEW [dbo].[tokens]
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
create view [dbo].[tokens] as
select
ps.name as [publisher],
p.publisher_db,
p.publication,
ss.name as [subscriber],
da.subscriber_db,
t.publisher_commit,
t.distributor_commit,
h.subscriber_commit,
datediff(second, t.publisher_commit, t.distributor_commit) as [pub to dist (s)],
datediff(second, t.distributor_commit ,h.subscriber_commit) as [dist to sub (s)],
datediff(second, t.publisher_commit, h.subscriber_commit) as [total latency (s)]
from mstracer_tokens t
inner join MStracer_history h
on t.tracer_id = h.parent_tracer_id
inner join mspublications p
on p.publication_id = t.publication_id
inner join sys.servers ps
on p.publisher_id = ps.server_id
inner join msdistribution_agents da
on h.agent_id = da.id
inner join sys.servers ss
on da.subscriber_id = ss.server_id
I leave it as an exercise to the reader to turn that into monitoring. I'd give you what I have, but recently realized that it has a bug in it. But things to keep in mind:
- A given publisher may not have had any tokens posted in the time frame that you're looking for. That should be flagged
- As a measure of latency, you want the publisher_commit time for the most recent token to commit to the subscriber
Good luck!
