2.3 monitoring



  • How can we generate a graph for a time period in the past? We used to do that under "custom" tab till version 2.2.6

    Thanks



  • Custom time periods capability is not available in 2.3.  It is available in 2.3.1 though.

    In 2.3.1 there is a custom option in the time period drop down. Select that and the start/end fields will appear.

    there is a gif in the development thread: https://forum.pfsense.org/index.php?topic=110388.0



  • Thanks. You saved me. I upgraded to 2.3.1 and got the custom ranges. We need this for a dispute with our ISP regarding the connection quality.

    I am using screenshots to save the graphs but "Export as / Save as" a picture would be a nice addition to "Export as CSV" (Feature request)

    Thanks.



  • I thought there was a CSV export option when selecting your graph parameters. Not at home, can't remember for sure.

    There is an export to CSV, I believe Ragai was asking for an Export Graph Image in addition to the CSV option. If so, the graphs are generated on the client side, you'll just have to take a screenshot to get an image.



  • You are correct jdillard. I thought that "Export As Image" would be a nice addition to the existing "Export As CSV" feature in case one needs to export quite a few graphs to demonstrate an issue.

    I am not a web programmer so please ignore my request if it would require too much time & effort.

    No worries. It's just that the graphs are rendered in the browser so the server doesn't have a graph to render, just numbers in a database. One of the reasons for removing the old RRD graphing was because the server-side graphing libraries were going to double the size of the overall image, which wasn't cool. Developing a workflow for screenshots isn't too difficult and there are lots a handy tools out there. For instance, on OSX you just need to hit command+shift+4.



  • @jdillard:

    Anybody has an idea what are the values in the first column? The next columns are "packet loss", "delay average", ""delay std. dev.", but the first column header is missing.
    I was guessing it's Unix timestamp, but it's not, because a calculation from that number gives errorneous results.
    I need to present a log to my boss, and I can't decode timestamps to absolute time values…

    It's UNIX time with three extra digits on the end for sub-second precision (not that RRD really needs it…)
