Managing TigerGraph Servers with gadmin

Contents of this Section:

Introduction

TigerGraph Graph Administrator (gadmin) is a tool for managing TigerGraph servers. It has a self-contained help function and a man page, whose output is shown below for reference. If you are unfamiliar with the TigerGraph servers, please see GET STARTED with TigerGraph .

To see a listing of all the options or commands available for gadmin, run any of the following commands:

$ gadmin -h $ man gadmin $ info gadmin


After changing a configuration setting, it is generally necessary to run gadmin config-apply. Some commands invoke config-apply automatically. If you are not certain, just run config-apply

Command Listing

Below is the man page for gadmin. Most of the commands are self-explanatory.

Examples

Checking the status of TigerGraph component servers:

Use "gadmin status" to report whether each of the main component servers is running (up) or stopped (off).  The example below shows the normal status when the graph store is empty and a graph schema has not been defined:

$ gadmin status

=== zk ===
[SUMMARY][ZK] process is up
[SUMMARY][ZK] /home/tigergraph/tigergraph/zk is ready
=== kafka ===
[SUMMARY][KAFKA] process is up
[SUMMARY][KAFKA] queue is ready
=== gse ===
[SUMMARY][GSE] process is down
[SUMMARY][GSE] id service has NOT been initialized
=== dict ===
[SUMMARY][DICT] process is up
[SUMMARY][DICT] dict server is ready
=== graph ===
[SUMMARY][GRAPH] graph has NOT been initialized
=== restpp ===
[SUMMARY][RESTPP] process is down
[SUMMARY][RESTPP] restpp has NOT been initialized
=== gpe ===
[SUMMARY][GPE] process is down
[SUMMARY][GPE] graph has NOT been initialized
=== glive ===
[SUMMARY][GLIVE] process is up
[SUMMARY][GLIVE] glive is ready
=== Visualization ===
[SUMMARY][VIS] process is up (WebServer:2254; DataBase:2255)
[SUMMARY][VIS] Web server is working


Stopping a particular server, such as the rest server (name is “restpp"):

$ gadmin stop restpp


Changing the retention size of queue to 10GB:

$ gadmin --set -f online.queue.retention_size 10

Updating the TigerGraph License Key

A TigerGraph license key is initially set up during the installation process. If you have obtained a new license key,  run the command

gadmin set-license-key <new_key>


to install your new key. You should then follow this with

gadmin config-apply



Example: Setting the license key

$ g admin set-license-key new_license_key

[RUN ] /home/tigergraph/.gsql/gpe_auto_start_add2cron.sh
[RUN ] /home/tigergraph/.gsql/all_log_cleanup_add2cron.sh
[RUN ] rm -rf /home/tigergraph/tigergraph_coredump
[RUN ] mkdir -p /home/tigergraph/tigergraph/logs/coredump
[RUN ] ln -s /home/tigergraph/tigergraph/logs/coredump /home/tigergraph/tigergraph_coredump

$ gadmin config-apply
