Managing with gadmin

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.

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

$ gadmin -h
$ gadmin --help

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
gadmin config apply

List of commands

Below is the man page for gadmin. Most of the commands are self-explanatory. Common examples are provided with each command.

Some commands have changed in v3.0. In particular,
gadmin set <config | license>
has changed to
gadmin <config | license> set

gadmin autocomplete

Gadmin autocomplete is more of a feature than a command. It is an auto-complete feature that allows you to see all possible entries of a specific configuration. You can press tab when typing a command to either print out all possible entries, or auto-complete the entry you are currently typing.

$ gadmin autocomplete -h

Generate autocomplete script

Usage:
  gadmin autocomplete <bash|zsh> [flags]

Description:
  If you want to make this automatic, add ". <(gadmin autocomplete bash)" to your
  .bashrc file.

Flags:
  -h, --help   help for autocomplete

Global Flags:
      --debug   enable debug log output to stdout

The example below shows an example of the autocomplete for the command gadmin status.

tigergraph@ubuntu:~$ gadmin status

Global Flags:

Generating a license seed

To generate a license seed, use the following command:

$ gadmin license seed <host_signature_type>
# host_signature_type: [aws|azure|gcp|hardware|node-id]

Depending on your host machine, you need to choose the appropriate host signature type. If you are generating the seed from a cloud instance, choose the corresponding cloud provider as your signature type.

If you are generating the seed from your own machine, choose either node-id or hardware.

  • The hardware option tells gadmin to collect information from your machine’s hardware as the host signature to generate the license seed. A signature produced by using this parameter will not be altered by software changes on the machine, including OS reinstalls. This is the usual choice.

  • node-id refers to the machine ID in the machine-id file located at /etc/machine-id and is a unique signature for the OS that identifies your machine. A reinstall of the OS may change the machine ID.

Applying a new license key

Example flow for applying a new license (which may be replacing an existing license key):

$ gadmin license set <new_license_key>
[   Info] Configuration has been changed.
Please use 'gadmin config apply' to persist the changes.

$ gadmin config apply
[Warning] No difference from staging config, config apply is skipped.
[   Info] Successfully applied configuration change. Please restart services to make it effective immediately.

$ gadmin restart
[   Note] Restart the service(s)? (y/N)y
[   Info] Stopping DICT ADMIN GSE NGINX GPE RESTPP KAFKASTRM-LL KAFKACONN TS3SERV GSQL TS3 GUI
[   Info] Starting ZK ETCD DICT KAFKA ADMIN GSE NGINX GPE RESTPP KAFKASTRM-LL KAFKACONN TS3SERV GSQL TS3 GUI

Once the license has been set and config has been applied, you can run gadmin license status to view the details of your license, including the expiration date and time.

$ gadmin license status
[Warning] License will expire in 6 days

  • Warmup - The service is processing the graph information and will be online soon.

  • Stopping - The service has received a stop command and will be down soon.

  • Offline - The service is not available.

  • Down - The service has been stopped or crashed.

  • StatusUnknown - The valid status of the service is not tracked.

Process State Status Definitions

  • Init - Process is initializing and will be in the running state soon.

  • Running - The process is running and available.

  • Zombie - There is a leftover process from a previous instance.

  • Stopped - The process has been stopped or crashed.

  • StatusUnknown - The valid status of the process is not tracked.

gadmin stop

The gadmin stop command can be used to stop one, many, or all TigerGraph services. You will need to confirm the restarting of services by either entering y (yes) or n (no). To bypass this prompt, you can use the -y flag to force confirmation.

$ gadmin stop -h

Stop services by service id

Usage:
  gadmin stop [serviceID...] [flags]

Description:
  ServiceID should be [serviceName][_partition][#replica], e.g., GSE_1#3. Leave
  replica field empty(e.g. GSE_1) to either refer to all replicas of given
  partition, or if the service has no replicas(e.g. EXE_1). Same for parititons.
  If no serviceID is specified, it only stops services excluding the
  infrastructure. Use 'gadmin stop all' to stop all services.

Flags:
  -y, --confirm   confirm to stop service
  -h, --help      help for stop
  --ignore-error  stopping services with ignore-error will stop all possible services, and ensure that the platform can still stop and run normally when some services or some nodes are down

Global Flags:
      --debug   enable debug log output to stdout
$ gadmin stop gsql
[   Note] Stop the service(s)? (y/N)y
[   Info] Stopping GSQL

gadmin version

$ gadmin version -h

Show the version information

Usage:
  gadmin version [flags]

Description:
  Show version information of all TigerGraph components, including repo name,
  version, git commit number, git commit datetime.

Flags:
  -h, --help   help for version

Global Flags:
      --debug   enable debug log output to stdout

Configuring memory use thresholds

TigerGraph offers two levels of memory thresholds using the following configuration settings:

SysAlertFreePct and SysMinFreePct

SysAlertFreePct setting indicates that the memory usage has crossed a threshold where the system will start throttling Queries to allow long-running queries to finish and release the memory.

SysMinFreePct setting indicates that the memory usage has crossed a critical threshold and the Queries will start aborting automatically to prevent GPE crash and system stability.

By default, SysMinFreePct is set at 10%, at which point Queries will be aborted.​

$ gadmin config entry GPE.BasicConfig.Env

GPE.BasicConfig.Env [ LD_PRELOAD=$LD_PRELOAD; LD_LIBRARY_PATH=$LD_LIBRARY_PATH; ]: The runtime environment variables, separated by ';'
✔ New: LD_PRELOAD=$LD_PRELOAD; LD_LIBRARY_PATH=$LD_LIBRARY_PATH;

Add this line to the existing config :
SysMinFreePct=20;SysAlertFreePct=70;

Your config line should now look like this :

GPE.BasicConfig.Env [ LD_PRELOAD=$LD_PRELOAD; LD_LIBRARY_PATH=$LD_LIBRARY_PATH; ]: The runtime environment variables, separated by ';'
✔ New: LD_PRELOAD=$LD_PRELOAD; LD_LIBRARY_PATH=$LD_LIBRARY_PATH;SysMinFreePct=20;SysAlertFreePct=30;

$ gadmin restart gpe -y

Example:

SysAlertFreePct=30 means when the system memory consumption is over 70% of the memory, the system will enter an alert state, and Graph updates will start to slow down.

SysMinFreePct=20 means 20% of the memory is required to be free. When memory consumption enters a critical state (over 80% memory consumption) queries will be aborted. automatically.
