<p class="MsoNormal"><span style="color:black">Hi,<br>
<br>
I've got some strange issues with a web application, where it loses connectivity at a certain time each night. After a bit of investigation, I think that this might be related to network congestion. i.e. the backups are taking up all of the available bandwidth
and as a result the web app connections time out.<br>
<br>
I'd like to use a plugin to monitor the amount of bandwidth which is being used by the server as a whole to see if it is ever saturated. e.g. if bandwidth remains at 90% of 1Gb/s send a warning<br>
<br>
Does anyone know of a plugin which would allow me to monitor this?<br>
<br>
Thank you<br>
Serge</span></p>
