![]() Problems with opening and working with DGR files are most probably having to do with no proper software compatible with DGR files being present on your machine. The list below will guide you through the process of addressing the encountered problem. Fortunately, most common problems with DGR files can be solved without in-depth IT knowledge, and most importantly, in a matter of minutes. This type of graph is convenient for comparing the present value with the value from the previous days or weeks.Ī comparison graph has been supported on the search page for a long time.Being unable to open files with DGR extension can be have various origins. This same feature is now available for the dashboard too. We recently introduced a new timeshift operator as a way to shift the original query time range within complex expressions. Let's use the log volume dashboard to demonstrate how timeshift works. First, navigate to the log volume dashboard and click on "Add Graph". Mean(value where tag='logVolume' metric='logBytes') I set the name of the graph to "Log Volume Trend" and create three plots on the graph. ![]() Mean(value timeshift 1d where tag='logVolume' metric='logBytes') This plot shows the mean value of log volume in bytes. Mean(value timeshift 1d where tag='logVolume' metric='logBytes') - mean(value where tag='logVolume' metric='logBytes') This is the timeshifted plot that shows the log volume during the same time range from 1 day ago. This last plot shows the differences in log volume in bytes between yesterday and today.Īfter saving the config to the dashboard, my "Log Volume Trend" graph shows 3 lines for the three district plots. Having 3 plots on the same graph is a bit redundant, so you should probably keep just one plot "log volume diff" since it offers pretty much the same information. Old syntax: mean:5m:1w(bytes where path = '/home') < 100 Note that the alerts support similar functionality using an alert-specific syntax. Mean:5m:1w(bytes timeshift 1w where path = '/home') < 100 When the new syntax collides with the old syntax : New syntax: mean:5m(bytes timeshift 1w where path = '/home') < 100īoth syntaxes will remain valid for alerts. This will result in an alert to query the time interval by two weeks.Home computer tips charts that pack a punch bygone beepers. ![]() Ome computer users are especially vulnerable to viruses, worms and hackers. Such malicious activity can disable your computer and destroy irreplaceable data. ![]() Without protection, hackers can take control of your system. Worse, they can use your system to attack others.
