openHAB <-> InfluxDB no communication

Add-ons Persistence Services
1

Dear comunity I need your help…

I set up InfluxDB at one PC and openHAB at an other one. Both are in the same network and can see each other.

Version:
openHAB 1.8.3
Addon:
org.openhab.persistence.influxdb-1.9.0-SNAPSHOT.jar

InfluxDB 0.13

Config:
openhab.cfg
influxdb:url=http://192.168.2.211:8086
influxdb:user=openhab
influxdb:password=openhab
influxdb:db=openhab
influxdb:retentionPolicy=default

When I start openHAB
[INFO ] [c.internal.ModelRepositoryImpl] - Loading model ‘influxdb.persist’
[DEBUG] [xDBPersistenceServiceActivator] - InfluxDB persistence bundle has been started.
[DEBUG] [i.i.InfluxDBPersistenceService] - influxdb persistence service activated
[ERROR] [i.i.InfluxDBPersistenceService] - influxdb:password

regular I can see this message:
[WARN ] [i.i.InfluxDBPersistenceService] - Configuration for influxdb not yet loaded or broken.

I monitored with tcpdump but don’t see any communication between InfluxDB and openHAB during startup.
Using curl I can save data into influxDB, and I can see the packages at tcpdump

curl -i -XPOST http://192.168.2.211:8086/write?db=openhab --data-binary “HARDWARE,CPU=“1” value=91, CPU=“2” value=92 1422568543702900257”

can someone give me a hint what the error message is all about?
[ERROR] [i.i.InfluxDBPersistenceService] - influxdb:password

thanks

Do you have an influx.persist file?

I am having similar issues, influxdb seems to be working and if I run Openhab in debug mode i see
20:04:39.254 [TRACE] [i.i.InfluxDBPersistenceService:239 ] - storing Temperature_Roof_Central in influxdb value 24.4, Temperature_Roof_Central (Type=NumberItem, State=24.40)
Here is my influxdb.persist file

Strategies {

// If no strategy is specified for an item entry below, the default list will be used.
everyMinute : "0 * * * * ?"
default = everyUpdate }

Items {

Temperatures* : strategy = everyUpdate, restoreOnStartup

}

Appreciate any help in trying to figure this out (note I’m using Openhab 1.8.3 and Influxdb v1.1.0)
Thanks
Rob

Try enabling debug logging and look for errors and other logging statements from InfluxDB, particularly when OH is first starting.

Thanks for the reply, I have enabled DEBUG and TRACE logging and see the following when is start OH

2016-11-17 08:49:00.011 [TRACE] [i.i.InfluxDBPersistenceService] - Tried to get item from item class class org.openhab.core.library.items.NumberItem, state is 25.90_
2016-11-17 08:49:00.011 [TRACE] [i.i.InfluxDBPersistenceService] - found fractional part_
2016-11-17 08:49:00.011 [DEBUG] [i.i.InfluxDBPersistenceService] - got DecimalType value 25.9_
2016-11-17 08:49:00.011 [TRACE] [i.i.InfluxDBPersistenceService] - storing Temperature_Roof_Central in influxdb value 25.9, Temperature_Roof_Central (Type=NumberItem, State=25.90)_

Here are my openhab.cfg influxdb config items

persistence:default=influxdb
influxdb:url=http://192.168.0.103:8086
influxdb:user=openhab
influxdb:password=openhab
influxdb:retentionPolicy=autogen

Well the logs imply that there is communication going on. OH retrieved 25.9 for Item Temperature_Roof_Central. I’m assuming you have restoreOnStartup?

You were right, it’s not OpenHab related. I set influxdb up on another server and pointed OH at it and that works. Going to try removing influxdb and doing a fresh install. Thanks
