Download the Binaries and Docker Images and Load Them

Download the jars, hystaller, accelo binaries, and docker images from the download links provided by Acceldata.
Move the docker images and jars in the following directory:

Bash

mkdir -p /data01/images
Copy

Copy the binaries and tar files in to the /data01/images folder.

Bash
    
xxxxxxxxxx
 
cp </path/to/binaries/tar> /data01/images
Copy

Change the directory.

Bash
    
xxxxxxxxxx
 
cd /data01/images
Copy

Extract the single tar file.

Bash
    
xxxxxxxxxx
 
tar xvf <name_of_tar_file>.tar
Copy

Bash
    
xxxxxxxxxx
 
source /etc/profile.d/ad.sh
Copy

Run the init command to provide the Pulse version.

Bash
    
xxxxxxxxxx
 
accelo init
Copy

OUTPUT

Bash
    
xxxxxxxxxx
 
[root@nifihost1:~ (ad-default)]$ accelo initEnter the AccelData ImageTag: : 3.3.3✓ Done, AccelData Init Successful.
Copy

Configure Gauntlet

Updating the Gauntlet Crontab Duration

Check if the ad-core.yml file is present or not by running the following command:

Bash
    
xxxxxxxxxx
 
ls -al $AcceloHome/config/docker/ad-core.yml
Copy

If the above file is not present, then generate it by running the following command:

Bash
    
xxxxxxxxxx
 
accelo admin makeconfig ad-core
Copy

Edit the ad-core.yml file.

a. Open the file.

Bash
    
xxxxxxxxxx
 
vi $AcceloHome/config/docker/ad-core.yml
Copy

b. Update the CRON_TAB_DURATION env variable in the ad-gauntlet section.

Bash
    
xxxxxxxxxx
 
CRON_TAB_DURATION=0 0 */2 * *
Copy

This makes gauntlet run every two days at midnight.

c. The updated file will look something like this:

Copy

Updating the Gauntlet Dry Run Mode

Check if the ad-core.yml file is present or not by running the following command:

Bash
    
xxxxxxxxxx
 
ls -al $AcceloHome/config/docker/ad-core.yml
Copy

If the above file is not present, then generate it by running the following command:

Bash
    
xxxxxxxxxx
 
accelo admin makeconfig ad-core
Copy

Edit the ad-core.yml file.

a. Open the file.

Bash
    
xxxxxxxxxx

Copy

b. Update the DRY_RUN_ENABLE env variable in the ad-gauntlet section.

Bash
    
xxxxxxxxxx
 
DRY_RUN_ENABLE=false
Copy

This will make the gauntlet delete the older elastic indices and MongoDB data.

c. The updated file will look something like this:

Bash
    
Copy

d. Save the file.

Restart gauntlet service by running the following command:

Bash
    
Copy

Configuring Gauntlet for Multi Node and Multi Cluster Deployment

Run the following command to generate the gauntlet config files:

Updating MongoDB Cleanup and Compaction Frequency in Hours

By default, when dry run is disabled MongoDB cleanup and compaction will run once a day. To configure the frequency, follow the steps listed below:

Run the following command:

Bash
    
Copy

Answer the prompts. If you’re unsure about how many days you wish to retain, then proceed with the default values.

Bash
    
Copy

When the following prompt comes up, specify the hours of the day during which you would like MongoDB clean up and compaction to run. The value must be a CSV of hours as per the 24 hour time notation.

Bash
    
Copy

Run the following command. When gauntlet runs the next time, MongoDB clean up and compaction will run at the specified hours, once per hour.
