New to IronMail and tasked to figure out why there are gaps in the dashboard charts(both queue and system). Please help explain what it is and where to look for answers/fix.
Appreciated your help.
You may want to call into support for this.
I have seen where disk I/O ramps up if you use the "Update Status" portlet in the dashboard. This portlet launches a program that checks the current updates, most notably the AV DAT files, it does require significant resouces and, along with the other portlets, it updates every minute. By itself, it doesnt cause much of an issue, however if multiple users are logged in or if the box is set to automatically update it may cause a delay.
You can remove this portlet by clicking on "Configure Dashboard View" (the button with the screwdriver and wrench in the top right) and then putting it back into the list in the center column.
I've talked to Support and they provide a workaround for now that seems to reduce the frequency of this issue. Workaround is in KB75357.
Installed it on both our appliances and it actually cut down on the frequency of the issue.
