Update Install

This section steps through an update installation for GroundWork Monitor 8.0.1. The Update Install is an offline method, it does not require internet access, and uses a distributed GroundWork Installer file to install.

Prepare and Run

1. First, check your system is prepared as described in System Requirements, including installing Docker CE and Docker Compose.
2. Review the Release Notes for the version you are upgrading to, which contain details of issues fixed, new features, and items of interest to those users who have customized or significantly enhanced a previous version of GroundWork Monitor. 

3. The Installer method of installation supports updates, and  running the Installer will update an existing GroundWork Monitor installation.

   It is recommended you perform a backup before updating your installation. 

4. Open a command line to the directory where you installed GroundWork Monitor 8. This is the directory above the gw8 directory. Check with an ls command to be sure. You should see the gw8 directory listed. 
5. Next, go to the Downloads page, navigate to and select the Installer file for the new version and place it in this directory.

6. Change the installer mode:

   chmod +x gw8setup-8.0.1-GA.run

7. If you are running the optional NeDi netflow or nfpcapd containers, stop them manually: 

   docker ps |grep nfcapd
   docker ps |grep nfpcapd

   This will give you the container name as the last column in the output, for example: 
   

   e5a971431d05      groundworkdevelopment/nedi:8.0.0-GA     "nfpcapd -i eth0 -T …"   49 minutes ago      Up 49 minutes (health: healthy)      nfpcapd_capture  

   Usually, these are nfcapd_collector (for NetFlow) and nfpcapd_capture (for packet capture). For each of these containers, type: 
   

   docker stop <name>

   where <name> is the name of the container, e.g., nfcapd_collector

8. Run the installer: 

   ./gw8setup-8.0.1-GA.run

9. The installer will function much as it does during a New Install, with the exception that it will not prompt for a host name if the host name is already set. The installer will shut down GroundWork, extract all the new containers, update the system and restart it.

10. If you want to run the optional NeDi netflow or nfpcapd containers again, start them with: 

    docker start nfcapd_collector
    docker start nfpcapd_capture

    or re-create them with this procedure NeDi Flowi NetFlow sFlow and packet capture.

Migrate Install

Migrating Monarch to GroundWork Monitor 8

This section steps through the migration process for GroundWork Monitor 8. Refer to the New Install tab from above to perform a new installation. After installation you can refer to the migration tasks on this page.

GroundWork Monitor 7.x

The following steps can be used to capture your existing GroundWork Monitor 7.x Nagios configuration database from your latest backup.

1. Access the command line on your Groundwork 7.x server, for example via SSH. We assume you are using a user that is not root, but has sudo access. If you use root, then you can omit the sudo part. 

2. Copy and paste the following command and run it:

   sudo tar -C /usr/local/groundwork/core/monarch/backup \
       -czf /tmp/$(ls /usr/local/groundwork/core/monarch/backup | tail -1).tar.gz \
       $(ls /usr/local/groundwork/core/monarch/backup | tail -1)

   This will produce a file such as /tmp/2018-12-26_16-44-47.tar.gz. This is the backup to be transferred. Note the date portion of the filename as the timestamp for the next steps, e.g., "2018-12-26_16-44-47" in this example. 

GroundWork Monitor 8

1. Transfer the backup you made above to the GroundWork 8 server. Place it in the gw8 directory. Use any secure method of transferring files you like, e.g., SCP. 

2. From the command line on the GroundWork 8 server, change to the gw8 directory:
   

   cd gw8

3. Substitute the appropriate timestamp from your captured filename and set it as the timestamp variable. For example (you will need to use your own timestamp):
   

   timestamp=2018-12-26_16-44-47

4. Copy and paste the following two commands to set the TAG variable and load the configuration:

   TAG=$(grep '^TAG=' .env | sed 's/^TAG=//')
   docker run --rm \
       -v ${PWD}/$timestamp.tar.gz:/$timestamp.tar.gz \
       -v dockergw8_monarch-backup:/usr/local/groundwork/monarch/backup \
       --name gw8 groundworkdevelopment/gw8:${TAG} \
       /src/docker_cmd.sh loadMonarchBackup $timestamp.tar.gz

5. In GroundWork Monitor 8, go to Configuration > Nagios Monitoring > Control > Back up and restore and proceed to restore the GroundWork Monitor 7.x backup with the noted timestamp.

Uninstall

Removing GroundWork Monitor 8

This uninstall process completely removes GroundWork Monitor 8, removing volumes and containers and the docker directory. It does not remove other docker containers and volumes that may exist on the same host. 

1. From the Docker directory you created when you installed GroundWork Monitor 8, go to the gw8 directory:

   cd gw8

2. Shut down the existing containers:

   docker-compose down

3. Remove GroundWork Monitor 8 volumes and containers:

   docker volume ls | grep "$(grep COMPOSE_PROJECT_NAME .env | sed -e 's/^[^=]*=//')_" | \
       awk '{print $2}' | xargs docker volume rm
   docker images -a | grep "groundworkdevelopment/" | \
       awk '{print $3}' | xargs docker rmi

4. Remove the docker directory:

   cd ..
   rm -rf gw8
