General Info

z/arch Enterprise Monitor AKA zEM is open source software that sends system events in real time to users hooked up to it via an Android cell phone or an Android watch.

Supervisors in constant contact such as:

• System Operators,
• System Admins
• Security Stuff
• Others with such a requirement and with assigned access.

Software works under z/Linux inside z/VM supervisor installed in LPAR or other z/VM. Connects with /dev/monreader assigned to Saved Sagment MONDCSS of z/VM memory area.

Two operational modes quite like CP *MONITOR service:

• Event
• Sample

Available approaches related to data gathering:

• just in real time sending msgs to connected clients via TCP/IP with no archive on DASD disks
• as above but with MINIMUM Event archive inside PostgreSQL database (remotly or on site)
• as above but with FULL Event & Sample archive inside PostgreSQL database (remotly or on site)
• Separate database for Event & Sample records (every record type inside their own table)

Technologies

• IBM mainframe
• z/VM
• z/Linux
• PostgreSQL database
• REST
• Rust (Actix Web, Tokio)
