Re: [Quickfixj-users] [ASK] Monitoring Connection in QuickFIX app

[Ajay P. <ap...@en...>]

We also use a similar timer construct rather than a listener to react
1) We run several hundred sessions and we have found it useful to do a
sweep and consolidate alerts if any,
2) There are network blips occasionally, especially on sessions that run
over the internet, and there is no point panicking unless connections are
unable to reconnect for extended periods or are repeatedly going down.

We also use the following
session.isSessionTime()  - useful to check if a session should be up
currently ie its not currently in its downtime
session.isEnabled()          - useful to check if an administrator has
knowingly disabled the session for whatever reason
