# Managing Logger Peers

Managed Loggers can be peered with any number of other Loggers. You can manage the peer relationship between Loggers in ArcMC. ArcSight recommends that, if possible, all peer Loggers be managed by ArcMC.

You can view peers; add or remove peers to a Logger; and import, edit, push, and delete peer groups. A peer group is a named set of Loggers you can use to organize and administer sets of Loggers more easily.

Note: For more information about Logger peering, please refer to the ArcSight Logger Administrator's Guide.

## Viewing Peers or Peer Groups

You can view the peers of a Logger managed by ArcMC, as long as the Logger is version 6.1 or later.

To view peered Loggers in ArcMC:

1. Select Configuration Management > Logger Peers. The Logger Peers table is displayed with all managed Loggers of version 6.1 or later.
2. To view the Loggers peered to a specific Logger in the list , in the Peer Loggers column, click the link indicating the number of peers. The filterable Peer Loggers dialog lists all the Logger's peers.
3. To view peer groups in ArcMC, click View Peer Groups.

## Adding or Removing Peers

You can add peers to, or remove peers from, a Logger managed by ArcMC, as long as the managed Logger is version 6.1 or later.

Note: If you remove a Logger not managed by ArcMC as a peer, you will not be able to add it back to the group unless you import the peer group including the Logger into ArcMC, or you add the removed Logger to ArcMC management.

To add peers to, or remove peers from, a Logger:

1. Select the Logger whose peers you wish to edit from the Logger Peers table.
2. Click Edit Peers.
3. All currently peered Loggers are shown.
   1. To add one or more peers, click Add Peers. Then, in the Add Peers dialog, select the Loggers to be added as peers. Optionally, to create a new peer group in ArcMC, in Peer Group Name, enter a name for the peer group. Then, click Add.
   2. To remove one or more Loggers as peers, select the Loggers to remove, and click Remove Peers. Click Yes to confirm removal as peers.

Note: For this release, Logger peering is supported using user name and password, not authorization code.

## Importing a Peer Group

You can import Logger peer groups into ArcMC. Importing a peer group is only supported on Loggers version 6.1 or later.

To import a peer group from a Logger (of version 6.1 or later):

1. Select Configuration Management > Logger Peers.
2. Click View Peer Groups.
3. Click Import Peers.
4. On the Select Peer dialog, select a managed Logger. (The selected Logger will also be part of the imported peer group.) Then, click Next.
5. On the Select Peer (of the Target) dialog, select one or more peers to import into ArcMC.
6. In Peer Group Name, enter a name for the selected peer group.
7. Click Import. The selected peer group is imported into ArcMC.

## Edit a Peer Group

You can edit a peer group, including the name, peered Logger hostname, and group members.

To edit a peer group:

1. Select Configuration Management > Logger Peers.
2. Click View Peer Groups.
3. Click the name of the peer group you wish to edit.
4. On the Edit Peer Group dialog, edit the peer group as needed. You can edit the peer group name, and add or remove peers from the group.
5. Click Save. Alternatively, click Save As... to save the peer group under a new name.

## Pushing a Peer Group

You can push a peer group to one or multiple managed Loggers of version 6.1 or later. The Loggers in the group will become peered with the managed Loggers to which you pushed the group.

To push a peer group:

1. Click Configuration Management > Logger Peers.
2. Click View Peer Groups.
3. From the table, select a peer group to push.
4. Click Push.
5. On the Destination Loggers dialog, select one or more destination Loggers to which to push the peer group.
