bitsmiths-monitor 2.1.5

The Bitsmiths Monitor Package

BITSMITHS MONITOR

The monitor is a light weight orchestration package where a system requires batch jobs to be run on a recurring basis. The monitor uses a relational database to track which jobs are to be scheduled, running, and have completed.

The main features are:

• Create batch schedules on a minute, hour, day, week, month, or yearly cycle.
• Batch schedules can have dependencies on one another.
• Limit the amount of concurrent running jobs.
• Overload the main classes to customize the package for your needs.
• Supports ad-hoc running of batch jobs.
• Stores a full run history of all your batch jobs.

This product has a dependency on:

• Mettle (bitsmiths-mettle)
• Bitsmiths Library (bitsmiths-lib)

Note that we package the generated Mettle code in this package, which means that the Mettle version required in this module is important.

Tables & Setup

Monitor is designed to use a relational database with a schema/namespace of monitor in your database. You will need to create this schema manually. It requires several other relational database tables.

The package provides the SQL code to create these tables. There are two ways to access the table creation SQL.

1. You can run bs-monitor -g postgresql at the command line, this will print all the SQL to stdout.
2. You can import the bs_monitor module and get the SQL as shown below:

import bs_monitor

print(bs_monitor.get_table_sql('postgresql'))

Note! Currently only postgresql SQL is added to the package. If you want us to support another database let us know and we will put it into the development pipeline.
