FIXEdge node management

Add node

User can add node to cluster by adding configuration information in configuration file and running playbook (see deployment manual).

Please be careful with deployment of database part in playbook. During initial deployment scripts in playbook create clean database structure. If you create playbook for adding node you must exclude database part, otherwise all data will be lost. It is strictly recommended to backup database before any actions with playbooks.

Remove node

To remove FIXEdge node user must do the following

  1. stop fixedge node ($sudo systemctl stop fixedge)
  2. remove healthcheck from Consul ($sudo rm /srv/consul-agent/etc/fixedge-respond-check.json). 
  3. Stop consul-agent service if you want to remove node from list of nodes in Consul GUI ($sudo systemctl stop consul-agent)

Node maintenance

Configuration

Sessions and schedules properties are managed via Configuration Service with the help of CLI tool. All other configuration parameters are managed via local property files similar to standalone FIXEdge (see)

Logs

FIXEdge node logs are collected in centralized storage - Splunk system. You can concern How to integrate FIXEdge with Splunk document.

User must create data source input on tcp port=1514, sourcetype=log4j

Cluster services management

Running several instances of services

Deployment of additional instances of services is implemented via playbook similar to adding of FIXEdge nodes. User can run several instances of Configuration Service. All instances are equal (there is no leader), users can use any of them. Consul Coordinator allows several instances of service running.   

Removing of services can be done in the same way as for FIXEdge nodes.

directory path for logs:

logs can be viewed by command

$journalctl -u configuration-service

Consul agent is deployed to each hardware unit to enable connection of cluster services with Consul server.

Session management

User can add, modify and remove sessions with Configuration Tool.

Schedule management

User can add, modify and remove schedules with Configuration Tool.

Troubleshooting 

Check health state of services and nodes

Health of nodes and services can be seen in Consul WebUI. Healthy services and nodes are displayed as below.



You can also check services state on hardware units where service or node is deployed to via Linux CLI commands.

$sudo systemctl status <service name>.

For example:

$sudo systemctl status fixedge

$sudo systemctl status consul-agent

Example of healthy service:

[user@ecsc00a02a94 etc]$ sudo systemctl status consul-agent
? consul-agent.service - Consul Agent
   Loaded: loaded (/usr/lib/systemd/system/consul-agent.service; enabled; vendor preset: disabled)
   Active: active (running) since Thu 2019-03-14 11:08:45 UTC; 21h ago
 Main PID: 18977 (consul)
    Tasks: 9
   Memory: 24.6M
   CGroup: /system.slice/consul-agent.service


Unhealthy node looks like

[user@ecsc00a03c92 ~]$ sudo systemctl status fixedge
? fixedge.service - FIXEdge Server
   Loaded: loaded (/usr/lib/systemd/system/fixedge.service; enabled; vendor preset: disabled)
   Active: inactive (dead) since Fri 2019-03-15 08:56:32 UTC; 2s ago
  Process: 12401 ExecStop=/srv/fixedge/bin/FixEdge1.stop.sh (code=exited, status=0/SUCCESS)
  Process: 10168 ExecStart=/srv/fixedge/bin/FixEdge1.run.sh (code=killed, signal=TERM)
 Main PID: 10168 (code=killed, signal=TERM)


adding node unsuccessful -  host unreachable

Problem:  when user tries to add new node running playbook  he gets error message similar to:

Description: node adding unsuccessful

Solution: Possible reason - node ip address is unreachable or user defined wrong ip address in configuration file. Check network connectivity and configuration file.
