Cannot save chart

[tbrandstetter]

I'm using Openhab 1.8 with the newest jars of Habmin:

org.openhab.binding.zwave-1.8.0.jar org.openhab.io.habmin-1.7.0-SNAPSHOT.jar org.openhab.ui.habmin_2.0.0.SNAPSHOT-0.0.15.jar

using the mysql persistence with following configuration:

// Persistence strategies have a name and a definition and are referred to in the "Items" section
Strategies {

    // If no strategy is specified for an item entry below, the default list will be used.
    default = everyChange 
}

/*
 * Each line in this section defines for which item(s) which strategy(ies) should be applied.
 * You can list single items, use "*" for all items or "groupitem*" for all members of a group
 * item (excl. the group item itself).
 */
Items {
    * : strategy = everyChange
}

on an Raspberry PI 2 +.

I have the Habmin and Habmin2 webapps in the webapps Folder (also the newest versions).

I can see the items and can also create charts, but I cannot save them. Habmin (and 2) says that it saved the charts but I cannot see them. In Habmin2 i can see that it is calling the /services/habmin/persistence/charts endpoint and posting a JSON request like:

{id: "1", name: "Test", title: "Test", period: "259200", legend: "false",…}
axis: [{position: "left"}, {position: "right"}]
id: "1"
items: [{item: "Strom_Gesamt", axis: "left", label: "Stromzähler gesamt"},…]
legend: "false"
name: "Test"
period: "259200"
title: "Test"

but afterwards the chart is gone. How can I debug what the problem is? It is not working in Habmin and Habmin2.

Maybe it's a permissions issue? If you're running on Linux, make sure that there's sufficient access rights to the OH folders?

[cdjackson]

Is this still an issue? I don't have any problem saving charts here so I suspect it's external to HABmin?

[tbrandstetter]

OH has been installed using the debian packages for it (on an Raspberry PI). If nobody else has this problem I think it has something to do with my setup. I'm going to refresh the whole installation and try it again. Sorry for the late reply.

[cdjackson]

Thanks for the info… It might be (I think) that the folders are slightly different when installed with apt-get. I’ve modified most of the resources to use the standard OH methods to get the folder, in which case this should be ok… I’ll leave this open to remind myself to double check the chart resource class…

I can confirm, I have same problem. Also standard debian installation. Where are charts stored? Debian installation runs under user:group habmin:habmin by default. I believe, permissions for this user are only set to directory /var/lib/openhab, which is OPENHAB_HOME_DIR. This is interesting part of openhab.in.sh from installation:

OPENHAB_CONF_DIR="/etc/openhab"
OPENHAB_CONFIGURATIONS_DIR="${OPENHAB_CONF_DIR}/configurations"
OPENHAB_DIR="/usr/share/openhab"
OPENHAB_LOG_DIR="/var/log/openhab"
OPENHAB_HOME_DIR="/var/lib/openhab"
OPENHAB_USER_DATA_DIR="${OPENHAB_HOME_DIR}"
OPENHAB_WORKSPACE_DIR="${OPENHAB_HOME_DIR}/workspace"
JETTY_CONFDIR="${OPENHAB_CONF_DIR}/jetty/etc"

however, most of dirs are owned by root:

Could this be the problem?

I'm also having trouble saving charts. It says that the chart has been save successfully. But it doesn't display it under the charts menu. When I go to add a chart widget to a dashboard I the saved chart in the list. But when I select it and hit save, nothing happens and I'm left with an empty widget. Sometimes I get an error message in the top right corner of the screen %%KEY NOT FOUND%%.

I'm using OH2, Habmin2, RPi2 and an rrd4j Persistence

[cdjackson]

It doesn’t sound like you have a problem saving charts - it sounds like there’s another problem? Have you set the default persistence in the user settings?

[miosolHH]

I've tried, but if I go back to the users tab, the setting isn't saved. Changing languages works though.

[cdjackson]

It does save the setting, but it’s not displaying when you go back. To fix this you can use the latest snapshot, but the current version does save the setting.

[miosolHH]

Ah ok, that's good to know. Ok, the charts now appear and are selectable as charts in the Dashboard.

The gauges in the dashboard don't have any selectable attributes though. I guess that is currently being discussed in #164 .

[cdjackson]

I believe that this issue is related to file permissions or something similar with some configurations so will close this. If there's anything concrete that can be suggested to help this in HABmin please reopen, or open a separate issue.

Got it. OH 1.8.3 (debian packages) on jessie, latest habmin1. Write access for openhab user in /etc/openhab/jetty/etc/ is needed. habmin stores its graphs in /etc/openhab/jetty/etc/habmin/charts.xml
