Managing with gadmin

Managing TigerGraph Servers 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. 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
$ 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

Command Listing

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

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

GADMIN(1)

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
admin         exe           ifm           nginx
all           gpe           infra         restpp

  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.

  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 starts services excluding the
  infrastructure. Use 'gadmin start all' to start all services.
​
Flags:
      --dry-run              dry run and output command to start the service
  -h, --help                 help for start

​
Show current status of service
​
Usage:
  gadmin status [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 will show all service status
​
Flags:
  -h, --help      help for status
  -v, --verbose   report service status in detail
​
Global Flags:
      --debug   enable debug log output to stdout

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

You can also check the status of each instance using the verbose flag : gadmin status -v or gadmin status --verbose. This will show each machine's status. See example below

$ gadmin status -v GPE
​
+--------------------+-------------------------+-------------------------+
|    Service Name    |     Service Status      |      Process State      |
+--------------------+-------------------------+-------------------------+
|      GPE_1#1       |         Warmup          |         Running         |
|      GPE_1#2       |         Warmup          |         Running         |
+--------------------+-------------------------+-------------------------+

Here are the most common service and process status states you might see from running the gadmin status command :

Service Status Definitions

  • Online - The service is online and ready.

  • 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 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 critical state (over 80% memory consumption) queries will be aborted. automatically.​
