QUESTION
Context: I am trying to compile a Go program (Specifically, the go-sigma-rule-engine by Markus Kont) to an executable so that I can upload it to AWS Lambda (which is Amazon Linux 2 under the hood I believe, according to this post.) and include/execute it via a Python Lambda function that issues shell/os commands to the rule engine program.
Problem: This program relies on many dependencies and for it to work with as few issues as possible I would like to statically link the program and compile, before uploading to AWS Lambda, so that all necessary dependencies are included within the executable itself.
Question: How do I statically link then compile a program in Go such that I target the AWS Lambda OS?
...ANSWER
Answered 2021-Dec-16 at 17:49This can be done via GOOS=linux go build .
Go builds statically linked executables by default so as long as the correct OS is targeted, you will get a binary that runs fine on AWS Lambda without having to include any specific libraries in the deployment package.
QUESTION
I recently started working with thingsboard in context of my bachelor-thesis. Right know I am trying out different functionalities in order to check which requirements thingsboard already satisfies and which have to be implemented by me.
Within that process I am stuck at the requirement that thingsboard dashboard should give live information about the connectivity status of a registered device (connected, disconnected, active, inactive).
To solve that I've tried out editing the rule chain used by the device profile assigned to the device of interest. Specifically I worked with the message type switch and tried out various action nodes connected to it via ConnectEvent, DisconnectEvent, ActiveEvent and InactiveEvent. What I would like to have is the connectivity status of the device to be stored in an SERVER_SCOPE attribute and then being displayed in the entity widget. All I've achieved is to generate an alarm when disconnected and cleared when (re)connected. I know there is a server side attribute called active that changes true immediately when device connects but it only turns false after the inactivityTimeout expired.
I also checked the ThingsBoard Device Connectivity Status page, the Create Alarm when the Device is offline guide and took long researches but couldn't get it to work.
Do you guys have any solutions or tips for me?
Kind regard.
...ANSWER
Answered 2021-Dec-01 at 15:28With the help of @JacksonB I managed to solve my problem.
What did I do?
Create a blue Transform-script node.
Change message type to
POST_ATTRIBUTES_REQUESTand add desired attributes. Here's my code for that:var newType = "POST_ATTRIBUTES_REQUEST"
msg.connectivity = "connected"
return {msg: msg, metadata: metadata, msgType: newType};
Than just connect this to an post attribute node in the rule chain like shown in the image. Link to screenshot of rule chain
No I am able to instantly see if a device is connected or disconnected by displaying the value of that attribute on my dashboard.
QUESTION
Context: I have a program (go-sigma-rule-engine by Markus Kont) on my EC2 instance that runs against a logfile and produces some output to screen.
The command used to run this program is ./gsre/go-sigma-rule-engine run --rules-dir ./gsre/rules/ --sigma-input ./logs/exampleLog.json
The program produces output of the form:

Answered 2021-Sep-22 at 22:05Maybe the output you want to capture goes to standard error rather than standard output. Try using 2> instead of > to redirect stderr.

I have the following bash command:
...ANSWER
Answered 2021-Aug-17 at 12:31You can add a sleep to the command you pass to xargs e.g. by wrapping it in sh -c ....
That's some horrible pipeline stringing, by the way. You can refactor grep -v foo | grep -v bar to grep -v -e foo -e bar or save the strings in a file and use grep -v -f filename; but let's further refactor everything into a single Awk script. See also useless use of grep.

I'm using the speech-rule-engine to generate English text from MathML. When trying to upgrade from v3.1.1 to v3.2.0 I'm seeing tests fail for reasons I don't understand.
I created a simple two file project that illustrates the issue:
package.json ...ANSWER
Answered 2021-May-12 at 13:41Problem solved, with the help of the maintainer of SRE. The problem is not in 3.2.0, but that jest does not wait for sre to be ready. The test was only correct by a fluke in 3.1.1 as the rules were compiled into the core. The following test fails with the above setup in 3.1.1 as well as the locale is not loaded:
QUESTION
We are using kafka for messaging and lot more stuff but now there is a requirement where we need some kind of rule-engine for data processing based on some rules. Does kafka holds any capability like this (rule-engine) or we have to use third party rule engine's (eg. https://camunda.com/dmn/ ) only and integrate with kafka.
...ANSWER
Answered 2020-Jul-28 at 13:26There is no need to use a third party rule engine with Apache Kafka. As part of the project there is Kafka Streams and also to ease off a bit the need to write Java code to express rules there is ksqlDB that is based on a subset of ANSI SQL.
While these options are not necessarily a rule engine per-se; they share the same semantics which is: given an intermediate processing output the relevant result based on the computation. The difference will be in the how and not in the what. So I think they are decent replacements.
You can always integrate both as well. Several rule engines such as Drools from Red Hat are Java-based and thus; can be easily accessed from a Kafka Streams processor. As long the if-then-else rules run in the same JVM space of the Kafka Streams application you won't have any performance penalties other than a possibly bigger JVM heap.
