Objective

This article explains how to check the status of the SYSTRAN services and its dependencies (from the web interface and the terminal). It also shows how to check their logs.

Prerequisites

SES 8.X or SPNS 9.X installed
Access to Advanced configuration > Translation resources page (you can ask your SystemAdmin to provide you with an access) : https://your_server_name.mysystran.com/advancedConfiguration/translationResources
Access to the terminal of the server hosting SYSTRAN (as root user)

List of the SYSTRAN services and its dependencies

SYSTRAN Services:

Systran Activity Collector (from SPNS 9.7)
Systran Corpus Manager
Systran DctIndexer
Systran Gdict
Systran Lookup
Systran Routing server
Systran Enterprise Server Console
Systran Enterprise Server File Translation Consumer
Systran Entreprise Server Translation Gateway
Systran Enterprise Server Poller
Systran TM-Indexer
Systran Translation Dispatcher
Systran Translation Resource Monitor
Systran Translation Resouce Store Console
Systran Translation Resource Store Poller

Third party dependency softwares:

MongoDB
RabbitMQ
Redis
Docker
Elasticsearch

Steps to follow

Check of status

There are two ways to check the status of the above stated Third party services and SYSTRAN components: from the web interface and from the terminal.

1. From the web interface

Go to the Avanced configuration tab of your menu, then choose Services: https://your_server_address/advancedConfiguration/services

Here, the SYSTRAN Enterprise Server Poller reports all information involving the system's status, of all components: RabbitMQ, MongoDB, Redis, Computing Node, Dispatcher, Routing Server etc.

The background color of each component indicates its status: green (running) to indicate success and red (fail) to indicate an error. If the SES Poller is not running or has not reported anything in some time, the background will be orange and a message that the 'status is not up to date' will be displayed.

2. From the server terminal

Below are a few commands:

- to list and check the status of all the SYSTRAN services:

systemctl -a | grep systran

- to start/stop/restart/status one particular SYSTRAN service:

systemctl [start/stop/restart/status] systran_service_name

- to start/stop/restart/status one dependency service:

systemctl [start/stop/restart/status] mongod 
systemctl [start/stop/restart/status] rabbitmq-server
systemctl [start/stop/restart/status] redis
systemctl [start/stop/restart/status] docker
systemctl [start/stop/restart/status] elasticsearch

Check of Systran services' logs

It is not possible to check them via the web interface. The terminal is needed.

Below are some commands:

- to show all SYSTRAN services' logs:

journalctl -fu systran-\*

- to show the log of one particular SYSTRAN service:

journalctl -u systran_service_name

Check the logs of Systran dependencies

The logs of each dependency service can be checked using the terminal.

MongoDB

Log files are located under /var/log/mongodb/
You can also do the command below to check the logs:

journalctl -u mongod.service

RabbitMQ

Log files are located under /var/log/rabbitmq/
You can also do the command below to check the logs:

journalctl -u rabbitmq-server.service

Redis

Log files are located under /var/log/redis/

You can also do the command below to check the logs:

journalctl -u redis.service

Docker

The logs of docker can be checked with the command:

journalctl -u docker

Elasticsearch

Log files are located under /var/log/elasticsearch/
