Status, settings and adding streamers

The Health menu section in the Watcher web UI allows the Watcher administrator to monitor streamer and disk statuses as well as configure and add streamers. By default, the local streamer is added to Watcher.

Before you add streamers to Watcher Cluster, you need to prepare them as described here. If you use Watcher Single, just configure the local streamer as needed.

Streamer status

To add streamer servers to Watcher:

  1. Click the Create a streamer button. The streamer settings page appears.

    Streamer settings

  2. Specify the streamer settings:

    • API URL - this url is used for internal communication between the Watcher server and the streamer. It shall conform to the specifications of the FQDN.

    • Public URL – used to connect with streams at the streamer. It shall conform to the specifications of the FQDN.

    • Cluster key – the cluster key used in the cluster (the cluster_key option in the configuration file). If the streamer’s and Watcher's cluster keys are identical, there is no need to fill this field.

    • DVR path – the path to the archive. This field is required for the archive to be recorded. For example: /dvr or @my_raid for Watcher RAID.

    • Bitrate limit – use if you need to limit the data transfer rate through the streamer, for example, when using it as a backup (failover).

    • Default – when you have added a number of streamers, you must select the default one. Check the Default box for one of the created streamers. All new cameras will be added to the default stream server.

    • Used as failover – you can enable the automatic use of any streamer as a redundant (backup) server for streams ingest in case of any other streamer fails (see Failover)

  3. Click Save.

The streamer appears in the list. Click the streamer host name to edit streamer settings.

If Watcher detects some errors or warnings in the server operation, the red or orange icon is displayed to the left of the hostname. Click the icon to view the error list, then click RESOLVE to fix the problem(s).

Caution

Identical date and time must be set on all servers in the cluster.
