Is it possible to check (in an existing replication) how often the replication agent is executed? (For example every 5 minutes, every 2 weeks,...)
I can't find it in the SQL-Server Agent.
You can use.
select * from MSlogreader_agents select * from MSdistribution_agents select * from MSdistribution_history select * from MSlogreader_history
in distribution database.
And to view schedule you can join MSlogreader_agents, MSdistribution_agents with msdb.dbo.jobschedules.
