You said:
Can you please provide an example message that does not work. Why is that so difficult? There are a lot of different issues discussed earlier and I want to make sure I understand exactly what you think should work.
The OP was trying to send this to the "influx out" node :
[
{
"time":1564134384,
"Concentration_C02":4080,
"Temperature":40.8,
"Relative_Humidity":102,
"Frame_Index":2
},
{
"Device":"test_datalog",
"Type_Produit":"Insafe_Carbon_Sigfox",
"Type_Message":"Datalog"
}
]
That's an array of objects.
It should have been an array of array(s) of objects :
[
[
{
"time":1564134384,
"Concentration_C02":4080,
"Temperature":40.8,
"Relative_Humidity":102,
"Frame_Index":2
},
{
"Device":"test_datalog",
"Type_Produit":"Insafe_Carbon_Sigfox",
"Type_Message":"Datalog"
}
]
]
The discussion around the time format issue is not relevant : if the node is configured to handle "ms precision" (actually resolution) it works perfectly with the timestamp provided.
The first one works perfectly for me

[Edit] Of course that is a silly time value, but if you set the precision to seconds in the influx node then it is good.
Didn’t had time yet to check what was wrong with my setup. Will confirm.
Make sure you are using the latest versions of node red and the influx node. A lot has changed since the start of this thread.
I write the data points (measurements) along with timestamps into influxdb on node-red, but unfortunately my data points are stored with host's timestamps only!
Here is my function to add timestamp to data:
timestamp= new Date().getTime() * 1e6;
topic_array = ['NodeID;ns=3;s="ExGrafanaDb"."MachineState1"."Data"."Mode"."TimeProduction"',
'NodeID;ns=3;s="ExGrafanaDb"."MachineState1"."Data"."Mode"."TimeProductionStart"',
'NodeID;ns=3;s="ExGrafanaDb"."MachineState1"."Data"."Mode"."TimeProductionEnd"'
];
meas_array = ['ExGrafanaDbMachineState1DataModeTimeProduction',
'ExGrafanaDbMachineState1DataModeTimeProductionStart',
'ExGrafanaDbMachineState1DataModeTimeProductionEnd'
];
function append_array(topic_array, meas_array, timestamp){
var totalCount = topic_array.length ;
//const appended_array = [];
//append dicts to array
for (var i = 0; i < totalCount; i++){
msg= {topic: topic_array[i],measurement: meas_array[i], timestamp: timestamp};
node.send(msg);
}
//return msg;
}
append_array(topic_array, meas_array, timestamp) ;
Node-Red Debug Logs:
The Data explored using Flux shows different timestamp than what is written from Node-Red:
Why is the timestamp not updated (different than in Node-Red) in the InfluxDB? What is wrong in here?
Please help, each suggestions/tips are very much appreciated!
Regards,
Mukara
You are using timestamp= new Date().getTime() * 1e6 so it is using the host time. You have shown us the timestamps in the database but haven't told us what timestamps you expect to see.
When pasting terminal output in future please use the </> button at the top of the forum entry window and paste the terminal output there.
I expect the timestamp printed on node-red debug log & influxdb should be same/identical (see both yellow marked texts)! But It is somehow varied what could be the problem here! See the above highlighted sections, the timestamp marked in nodered is different from timestamp marked in influxdb console!
Regards.
Mukara
Normally with the influxdb out node the time written is the current system time. If you want to pass in a time then look at the terminal output you posted and you will see that the field containing the timestamp is actually called time so if you want to write time and value then the payload must be something like
{time: 1655... , value: "2022-06-14 14:00:51"}
I used the key 'time' instead of 'timestamp' as you mentioned, now the flow doesn't even write to influxdb I guess:

What could be wrong here?
PS: even that key 'timestamp' doesn't work anymore, meaning no data with the (specific/modified) timestamp is stored to influxdb!

Mukara
The payload shown in your debug in the marked section does not look like the payload I suggested.
You may also find this online timestamp convertor useful. If you paste in the timestamp from influx it will tell you what that is in human readable form.
I guess its in the format as you suggested, instead of value its written as payload!

interesting information
No it isn't. For the format I suggested then in the debug output you should see something like
payload: {time: 1655283227811000000, value: "2090-01-01 00:00:00"}
The help text for the influxdb node explains the different formats available. If the payload just contains a string then that is written as the field value and time is set to the current system time.
Edit:
At least that is my understanding.
Yes, I agree the format is not yet correct!
I created a simple flow with static message (works) & with dynamic payload read from OPC server (doesn't work yet)!
I could see the difference in formats which works & which doesn't! I am still thinking how could I make it work! Please help if anybody knows how to resolve this formating issue!

Are you using the Batch node? I assumed you were using the normal influx out node.
If so then we have to start looking at the problem again, look at the help text for the node to see how it says to format the data.

I was trying to use the influxdb batch node, because if I use InfluxDB Out node, the timestamp is not written to the InfluxDB! Only in Batch Node I could write the timestamp along with the payload!

Does anybody know how to format the payload correctly, so that the Influx batch node accepts and stores the data/measurement with specified timestamp!
Here is my function to concatenate/format topic, measurement & timestamp (so far):
timestamp = new Date().getTime() *1e6;
function append_array(topic_array, meas_array, timestamp){
var totalCount = topic_array.length;
const appended_array = [];
//append dicts to array
for (var i = 0; i < totalCount; i++){
appended_array.push({topic: topic_array[i],measurement: meas_array[i], timestamp:timestamp});
}
return appended_array;
}
const topic_array = [
'NodeID;ns=3;s="ExGrafanaDb"."MachineState1"."Data"."Mode"."TimeProduction"',
'NodeID;ns=3;s="ExGrafanaDb"."MachineState1"."Data"."Mode"."TimeProductionStart"',
'NodeID;ns=3;s="ExGrafanaDb"."MachineState1"."Data"."Mode"."TimeProductionEnd"',
];
const meas_array = [
'ExGrafanaDbMachineState1DataModeTimeProduction',
'ExGrafanaDbMachineState1DataModeTimeProductionStart',
'ExGrafanaDbMachineState1DataModeTimeProductionEnd',
];
msg = append_array(topic_array, meas_array, timestamp);
return [msg];
Any suggestions are very welcome!

As I said you need to look at the docs for the node and see what it requires. Look at node-red-contrib-influxdb (node) - Node-RED (that link has been already been posted earlier in the thread). Look at the section on the batch node and it shows you how it should be formatted and gives some example flows that you can import.
