vital_servers (collection.cfg setting)


This option defines any number of servers which must exist in a web crawl for the update to successfully complete. The option is a comma-separated list of server names that are checked by the script to ensure content from this server has been crawled.

In practice, each listed server is checked against the servers.log file produced by the web crawler to ensure the vital server occurs in that file. If any servers are missing the swap does not take place and the update fails.

Note: No protocol (e.g. http or https) should be specified in the server name(s).
