SOLVED Time graph view showing always the same graph

[chonfirex]

Hi there, here goes my first post on this forum. Since awhile ago (I can't say precisely, but let's say 3 to 4 months) the time graph view show only one graph. It's configured to show 4 different graphs based on time period: "Daily (5 Minute Average)", "Weekly (30 Minute Average)", "Monthly (2 Hour Average)" and "Yearly (1 Day Average)". Nevertheless, all the for graphs shows a period of time I can't establish.

The graphs change depending on the graph. For instance, one of the devices being monitored has 2 graphs: CPU usage and Memory usage. If I visit the time graph view for CPU usage the graph displayed 4 times are all regarding CPU usage. If I visit the time graph view for Memory usage the graph displayed 4 times are all regarding Memory usage.

On the other hand, data are being polled regularly and it's being displayed without problems. Actually, if I set a custom period time (let's say 6 months), the graphs show everything fine. It makes me thing data are stored correctly in the database.

The system is running Fedora 29, rrdtool 1.5.5 and cacti 0.8.8h.

I send a screenshot.

Greetings,
Thank you so much.

You'll struggle getting support on 0.8.8h these days. The code has changed quite a lot.

I would check for any errors in the cacti.log or error_log (apache) as it sounds like something is not being calculated correct. Especially if you are able to set the time range manually and see data.

I found a solution. At graph.php, the case "view" seems not to be passing the parameters correctly. The values for graph_start and graph_end is needed to create the image. Nevertheless, it is not happening.

Around line 108 of graph.php there's this line of code:

Code: Select all

<img class='graphimage' id='graph_<?php print $_REQUEST["local_graph_id"] ?>' src='<?php print htmlspecialchars("graph_image.php?action=view&local_graph_id=" . $_REQUEST["local_graph_id"] . "&rra_id=" . $rra["id"]);?>' border='0' alt='<?php print htmlspecialchars($graph_title, ENT_QUOTES);?>'

The file graph_image.php has a series of if statements to check if some values needed to create the image have been passed. Two of these values are graph_start and graph_end. So, I added a couple of code to the previous line and now it looks like this:

Code: Select all

<img class='graphimage' id='graph_<?php print $_REQUEST["local_graph_id"] ?>' src='<?php print htmlspecialchars("graph_image.php?action=view&local_graph_id=" . $_REQUEST["local_graph_id"] . "&rra_id=" . $rra["id"] . "&graph_start=" . $graph_start . "&graph_end=" . $graph_end);?>' border='0' alt='<?php print htmlspecialchars($graph_title, ENT_QUOTES);?>'>

And everything is working great again.

On the other hand, I do believe I should upgrade the system, but, since it is a home PC, I don't want to go through it. Unless it's really, really necessary.

Greetings and thank you all.
