About ZEBRA and System Requirements

Zebra is an open source SW project under Linux Foundation's Open Mainframe Project's ZOWE Project. It intends to provide re-usable and industry compliant JSON formatted RMF/SMF data records, so that many other ISV SW and users can exploit them using Open-Source SW for many ways.

As an example and use-case, it shows real-time data and historical data in JSON format with time stamps. It can also store realtime data into MongoDB and Plot realtime Workload and CPU Utilization chart using Grafana. Zebra can be used to Parse static RMF Monotor I XML file into JSON.

• Required SW:

• Current version of Zebra requires RMF DDS Service(GPMSERV) running on IBM z/OS as source of the data
• NodeJS for runtime (This version tested with nodejs v8.11.2)

• Optional SW in case you like to test examples included in here:

• Grafana
• Prometheus
• MongoDB

Running Zebra

To Run Zebra, You'll need to:

• Set Up your Environment: You'll need to install nodejs (most prefered{v 8.11.x}), git and optional programs like Prometheus, MongoDB and Grafana. Optional programs will require proper licenses per their terms and conditions.

• Clone Zebra src code

• Install App packages using npm install from root directory, change set up using config files

• Run Zebra using npm, pm2, nodemon or any other nodejs process manager

(e.g. node bin/www)

Use Zebra

To Use Zebra, You'll need to configure the application parameters. These parameters can be configured by simply editing the Zconfig.json file in the root directory or using Zebra's /addsetting function while Zebra instance is running.

Configure Zebra Using Endpoint

Zebra’s configuration gives users the flexibility to run the app according to their needs. Zebra provides “/addsettings” endpoint for editing config values. This endpoint can take one or more parameters recognized by zebra at once. E.g.
http://localhost:3090/addsettings?appurl=127.0.0.1

Recognized Zebra Config Parameters

• ddsbaseurl: (Distributed Data Server base URL)
  This is the IP address of the DDS from which the App can retrieve RMF Data. E.g.
  http://localhost:3090/addsettings?ddsurl=127.0.0.1
• ddsbaseport: (Distributed Data Server base Port)
  This is the Port number of the DDS from which from which the App can retrieve RMF Data. E.g
  http://localhost:3090/addsettings?ddsport=8888
• rmf3filename: (DDS RMF Monitor III Filename)
  This is the filename from which The App can retrieve RMF Monitor III data. E.g.
  http://localhost:3090/addsettings?rmf3filename=rmfm3.xml
• rmfppfilename: (DDS RMF Monitor I Filename)
  This is the filename from which The App can retrieve RMF Monitor I data. E.g.
  http://localhost:3090/addsettings?rmfppfilename=rmfpp.xml
• mvsResource: (DDS RMF Monitor III resource identifier)
  This parameter represent Monitor III resource identifier. E.g.
  http://localhost:3090/addsettings?mvsResource=,SYS,RESOURCE
• mongourl: (Mongo DB URL)
  This is the IP address of MongoDB to which RMF III data will be saved. E.g.
  http://localhost:3090/addsettings?mongourl=127.0.0.1
• dbinterval: (Database Interval)
  This is the Interval for which data will be saved to MongoDB. Its unit is in seconds. E.g. Every 100 seconds
  http://localhost:3090/addsettings?dbinterval=100
• dbname: (Database Name)
  This is the name of the database for which RMF III data will be saved. E.g
  http://localhost:3090/addsettings?dbname=ompzebra
• appurl: (Running Zebra App URL)
  This is the IP address of running Zebra instance (after hosting). This value is needed for MongoDB, Prometheus and Grafana to work with Zebra. E.g. 127.0.0.1.
  http://localhost:3090/addsettings?appurl=127.0.0.1
• appport: (Running Zebra App Port)
  This is the Port of a running Zebra Instance (after hosting). This value is needed for MongoDB, Prometheus and Grafana to work with Zebra. E.g. 3000
  http://localhost:3090/addsettings?appport=3000
• mongoport: (Mongo DB Port)
  This is the port number of MongoDB to which RMF III data will be saved. E.g.
  http://localhost:3090/addsettings?mongoport=27017
• ppminutesInterval: (RMF Monitor I PP Report Interval)
  This is the Interval for which DDS Produce RMF I report. Its unit is in minutes E.g. Every 30 Minutes
  http://localhost:3090/addsettings?ppminutesInterval=30
• rmf3interval: (RMF Monitor III Report Interval)
  This is the Interval for which DDS Produce RMF III report. E.g. Every 100 seconds
  http://localhost:3090/addsettings?rmf3interval=100
• httptype: (http type of running Zebra App) This is the hypertext transfer protocol type of the running zebra app (after hosting). Its value is either http or https. E.g.
  http://localhost:3090/addsettings?httptype=http
• useDbAuth: ( Use Database Authentication) This config parameter determines the type of connection to mongodb, either with authentication or without authentication. Its value is either true or false. If value is set to true, zebra will require username and password with which to connect to mongodb. E.g.
  http://localhost:3090/addsettings?useDbAuth=true
• dbUser: (Database Username)
  This is mongodb username with which zebra will connect to database if value of useDbAuth is set to true. E.g.
  http://localhost:3090/addsettings?dbUser=salisuali
• dbPassword: (Database Password)
  This is mongodb password with which zebra will connect to database if value of useDbAuth is set to true. E.g.
  http://localhost:3090/addsettings?dbPassword=salisu
• authSource: (Authentication Source)
  This is mongodb database which contains the username and password for authentication. The default is mongodb’s “admin” database. E.g.
  http://localhost:3090/addsettings?authSource=admin
• useMongo: (Use Mongo DB)
  This parameter needs to be set to true before a user can connect MongoDB to Zebra. Its default value is false. E.g.
  http://localhost:3090/addsettings?useMongo=true
• usePrometheus: (Use Prometheus server)
  This parameter needs to be set to true before a user can connect Prometheus to Zebra. Its default value is false. E.g.
  http://localhost:3090/addsettings?usePrometheus=true
• https: (Use TLS)
  This parameter needs to be set to true before a user can use TLS for Zebra. Its default value is false. E.g.
  http://localhost:3090/addsettings?https=true

The user can specify multiple configuration parameters at once:
http://localhost:3090/addsettings?dbinterval=3600&appport=3000
The above URL contains two parameters dbinterval and appport. The user can specify as many parameters as possible with their value each. These new values specified by the user will overwrite the value stored in zebra’s config file.
