6.3 Checking the operating system processOnce we have checked the archive and our system view, we are ready to check the system process. Checking the system process may look a bit rough, but it proves to be very effective.On master, we can simply check a process called Wal_sender. On slave we want to check for a process called wal_receiver.Let's first examine what we should see on master:9314?? Ss 0:00.00 Postgres:wal Sender ProcessHS:: 1 (61498) idleOn Linux we can see that the process not only

Detailed installation and testing of pgwatch An error occurred during installation, but no documentation was found online. I decided to write a detailed installation document myself. 1. Download pgwatch. Here I use Version 1.0, as shown below: Wget http://www.cybertec.at/download/pgwatch/pgwatch-1.0.tar.gz 2. decompress and open the README file to check the installation requirements. The installation here is not described in detail. Tar-zxvf pgwatch-1.0.tar.gz Vim README ------------------------

? More than Checkpoint_segments * 2 + wal_keep_segments should not be used in the standard quota system of PostgreSQL for so many xlog files. If the number of xlog files starts to grow massively, you will encounter some strange problems. Make sure the Archive_command is working properly. If you perform these checks correctly, nothing bad happens in this area-if you can't check these parameters, you're not far from the danger.6.1.2
