The MSreplication_monitordata table contains cached data used by Replication Monitor, with one row for each monitored subscription. This table is stored in the distribution database.

Column name	Data type	Description
lastrefresh	datetime	Date and time that the monitor data was refreshed.
computetime	int	Is the time (in seconds) taken to compute monitor data.
publication_id	int	The publication ID.
publisher	sysname	The name of the Publisher.
publisher_srvid	int	The server ID of the Publisher.
publisher_db	sysname	The name of the publication database.
publication	sysname	The name of the publication.
publication_type	int	The type of publication, which can be one of these values: 0 = Transactional publication 1 = Snapshot publication 2 = Merge publication
agent_type	int	The type of replication agent, which can be one of these values. 1 = Snapshot Agent 2 = Log Reader Agent 3 = Distribution Agent 4 = Merge Agent 9 = Queue Reader Agent
agent_id	int	The ID of the replication agent.
agent_name	sysname	The name of the replication agent job.
job_id	uniqueidentifier	The GUID of the replication agent job.
status	int	Status of the replication agent, which can be one of these values: 1 = Started 2 = Succeeded 3 = In progress 4 = Idle 5 = Retrying 6 = Failed
isagentrunningnow	bit	A flag that indicates if the agent job is currently running, where a value of 1 means that the job is running.
warning	int	Threshold warning generated by a subscription, which can be the logical OR result of one or more of these values. 1 = expiration - a subscription to a transactional publication has exceeded the retention period by more than the allowable threshold, as a percentage of the retention period. 2 = latency - the time taken to replicate data from a transactional Publisher to the Subscriber exceeds the threshold, in seconds. 4 = mergeexpiration - a subscription to a merge publication has exceeded the retention period by more than the allowable threshold, as a percentage of the retention period. 8 = mergefastrunduration - the time taken to complete synchronization of a merge subscription exceeds the threshold, in seconds, over a fast network connection. 16 = mergeslowrunduration - the time taken to complete synchronization of a merge subscription exceeds the threshold, in seconds, over a slow or dial-up network connection. 32 = mergefastrunspeed - the delivery rate for rows during synchronization of a merge subscription has failed to maintain the threshold rate, in rows per second, over a fast network connection. 64 = mergeslowrunspeed - the delivery rate for rows during synchronization of a merge subscription has failed to maintain the threshold rate, in rows per second, over a slow or dial-up network connection.
last_distsync	datetime	The last date and time that the Distribution Agent ran.
agentstoptime	datetime	The date and time that the agent stopped.
distdb	sysname	Name of the distribution database for the subscription.
retention	int	The retention period for the publication.
time_stamp	datetime	Internal-use only.
worst_latency	int	The highest latency, in seconds, for data changes propagated by the Log Reader or Distribution Agents for a transactional publication.
best_latency	int	The lowest latency, in seconds, for data changes propagated by the Log Reader or Distribution Agents for a transactional publication.
avg_latency	int	The average latency, in seconds, for data changes propagated by the Log Reader or Distribution Agents for a transactional publication.
cur_latency	int	The latency, in seconds, for data changes propagated by the Log Reader or Distribution Agents during the current run.
worst_runspeedPerf	int	The longest synchronization time for the merge publication
best_runspeedPerf	int	The shortest synchronization time for the merge publication
average_runspeedPerf	int	The average synchronization time for the merge publication
mergePerformance	int	Performance of the last synchronization compared to all synchronizations for the subscription, which is based on the delivery rate of the last synchronization divided by the average of all previous delivery rates.
mergelatestsessionrunduration	int	Duration of the most recent Merge Agent run.
mergelatestsessionrunspeed	float(53)	Delivery rate of the most recent Merge Agent run.
mergelatestsessionconnectiontype	int	Connection used for the most recent Merge Agent session, which can be one of the following values: 1 = local area network (LAN) 2 = dial-up network connection
retention_period_unit	tinyint	Defines the unit used when defining retention, which can be one of these values: 1 = week 2 = month 3 = year
