I was looking for a more optimized way of loading the datapoints; perhaps through a CURL POST because trying to paste 2000 datapoints worth of data using a browser via the import/export can be slow.

Hello-

Does anyone have any tips to update the polling cycle interval on datapoints? For example, would like to change all the datapoints from 15 minute interval to 5 minute interval. Taking the import/export might be difficult as we currently have over 2000 points in a system.

Regards,

We had a little trouble with the path until we realized we needed to escape the slashes. For example: /rest/v1/realtime.json?like(path,/datacenter/5/room/4) would need to be sent as: /rest/v1/realtime.json?like(path,%2fdatacenter%2f5%2froom%2f4%2f)

Hello,

Using the new beta 1.6, trying to use REST/SWAGGER to query the latest real-time read data for multiple XID. For example, the query would be something like: ?XID0=DP_622107&XID1=DP_621502&XID2=DP_622361 and the return would be a set of the 3 values.

Thanks,

@jeremyh I'm swamped at work right but but will be happy to write up when I get a break, probably around 1July. Short story, we are a datacenter company and using the product as a backend data acquisition tool to provide energy and environmental (Critical and Essential) such as room temperature/humidity/air handler information. We have a various set of protocols ranging from ModBus, BacNet, SNMP, SQL, and custom SOAP calls and needed a one stop package that Mango provides. We have a front-end website that makes API calls to the Mango for data point retrieval.

we have about 14,000 currently loaded, with more on the way. The box is on a VmWare with 2 cores, 64-bit CentOs 7, Java 7, and 4 gig of memory. The TOP looks like this:

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
1352 root 20 0 3567912 2.229g 22884 S 33.6 60.2 246:32.96 java

I edited the ma-start.sh and changed the memory to 2048m. After doing so, the H2 cache was automatically increased from 54m to 115m. Will monitor for stability, but CPU use seems to be lower now. Below is the config entry:

$EXECJAVA $JPDA $JAVAOPTS -Xmx2048m -Xms2048m -server -cp "$MA_CP"
"-Dma.home=$MA_HOME"
"-Djava.library.path=$MA_HOME/overrides/lib:$MA_HOME/lib:/usr/lib/jni/:$PATH"
com.serotonin.m2m2.Main &

Are there any steps to increase the Java and H2 memory from the defaults? I have large number of points and API use and think increase in these to areas would be helpful. Running on linux Centos 7 with Java 7 and the H2.

Thanks,

Dan

I realized the "script" datasource would be sufficient. It would be cool to do some native SOAP calls, but this will get me through.

Hello-

I have a need to query a webService as a datasource. I could use a php or python script and curl/soap to output a value, but how would I go about creating a custom data source that would call a custom local script?

Thanks,

Hello-

Using the swagger REST API, is there a way to pass an array of XID to the point-values or the /v1/realtime api and the output would return a JSON set of results? Passing one XID per REST call seems like it would be too intensive. For example, I'd like to get the values of the points in a specific hierarchy. I can scrape the XID from the pointHierarchy and then iterate for each XID but that doesn't seem optimal. Any idea for improvement?

Thanks,

Dan
