How and what are the steps to deploy FglAM on a Microsoft clustered environment ?
Multiple instances of the Foglight Agent Manager can be run using a single Foglight Agent Manager bin directory.
In this type of configuration, multiple instances can be created and each instance uses a different state directory but runs from a single Foglight Agent Manager bin directory.
To setup FglAM on a Microsoft clustered environment:
1. Install the Foglight Agent Manager on each node in the cluster.
2. Initialize a state directory on the shared drive:
Once the Foglight Agent Manager installation is available to the nodes in the cluster, the next step is to initialize a state directory for an instance on the shared Network File System (NFS) drive that is used by the cluster.
When setting the state location locally from one of the nodes, you must define the full path to the remotely-mounted state directory.
For example:
fglam --create-state --location
f:\cluster_shared_dir\fglam_states\STATENAME_A
3. Launch the Foglight Agent Manager from the active node:
Run the Foglight Agent Manager from the active node and provide the full path to this instance’s state directory on the shared drive.
For example:
fglam --location f:\cluster_shared_dir\flgam_states\STATENAME_A
4. Deploy agents and create agent instances:
Once the Foglight Agent Manager is running, agents can be deployed to it and agent instances created. Files related to the runtime state for these agents (including log files) are stored under the remote state directory for this Foglight Agent Manager instance. Using the example above, they would be stored in f:\cluster_shared_dir\flgam_states\STATENAME_A\agents.
For example:
fglam --location f:\cluster_shared_dir\flgam_states\STATENAME_A
5. Ensure exclusive access to the shared state directory:
Ensure that only one instance of the Foglight Agent Manager that uses a particular state directory is running at a time.
Do not run two instances of the Foglight Agent Manager on separate machines (or separate active nodes in the cluster) and cause these instances to use the same shared state directory simultaneously.
