This is also one type of thing in which people are very interested. How to create probes other than PEM inbuilt probe? And how to create alert based on probe? Well answer is simple. Understand what probe is in PEM and then understand PEM Data detail. Probe in PEM requires following: 1. SQL Code which can be use to gathering data by pemagent. 2. Table in pemdata schema, which will be use for storing Current status/data of SQL. 3. History table (specially in pemhistory schema) where all history data will reside. Suppose user wants to monitor the Slony Replication using PEM (since, PEM doesn't have slony replication moniotring), so user can do following: 1. SQL Code which can be use for slony replication monitoring. We know that slony replication monitoring can be done using view sl_status of slony. So, user can create a SQL Code as given below for replication. select '_test_slony' as schema_name, st_origin,st_received, st_lag_num_events , st_lag_time from _test_slony

This is second post of Postgres Enterprise Manager 2.1 series. Question which people ask, Is Postgres Enterprise Manager tool useful for Companies, which provide services for PostgreSQL? Answer is yes. What about companies, which provide infrastructure support, where they provide server and PostgreSQL database, for them, is this is a good tool for monitoring PostgreSQL? Answer is yes, you can use it. Companies, which are giving Infrastructure support and providing Database As service always want everything to be automated. i.e with provisioning server, server should have installed PostgreSQL and its components plus they want automatic installation of pemagent, which is also acheivable. However, they stumped on Automatic Bidning of PEM Agent with PostgreSQL. For binding PostgreSQL with PEM Agent, Simple Method is using PEM Client. In PEM Client, Add a PostgreSQL in PEM Directory and then user can bind the PEM agent with PostgreSQL Cluster. File -> Add Server -> which will

Its being two months, that I didn't blog on any topic. So, I thought to share some information on PEM. This post is for users, who always look for type of inbuild alerts of PEM. In this Blog, I am listing categories of Alerts and List of alerts in each category, which one can find in Postgres Enterprise Manager 2.1. Also, if you have list of alerts then you can decide which alert you would like to configure. Postgres Enterprise Manager (PEM) is very useful tool for monitoring PostgreSQL and it has all the alerts which is require for monitoring postgresql. User can define this alerts in following categories: 1. Server Level Alerts. 2. PG Cluster Level Alerts. 3. Database Level Alerts. 4. Schema Level Alerts 5. Table Level Alerts. All the alerts which has been made/defined keeping in mind of postgreSQL. Let see what are the alerts in each categories: 1. Server Level Alerts: These alerts are made for monitoring Server Components like Memory,Disk and CPU and Server Level moni
