            Linux IP monitoring tool
            Asked 2022-Apr-08 at 16:12

            I need to get the IP numbers that are connecting to the EC2 instance then add them to AWS security group as a security group rule. So only those machines will have the permission to connect to instance. I don't need the port number that they're connecting to instance.

            I installed iptraf-ng but app is very slow on the instance. Any other suggestions to capture the connecting IP's to instance so I can add them faster to security group rule?



            Answered 2022-Apr-08 at 16:12

            You can use VPC Flow logs to monitor the traffic to the VPC (which will include the traffic that is going to the EC2 instance).



            how to check service running on other server with python
            Asked 2022-Mar-14 at 13:12

            I have a problem with checking my service on other windows or Linux servers.

            My problem is that I have to make a request from one server to the other servers and check if the vital services of those servers are active or disabled.

            I wrote Python code to check for services, which only works on a local system.



            Answered 2022-Mar-08 at 17:46

            As far as I know, psutil can only be used for gathering information about local processes, and is not suitable for retrieving information about processes running on other hosts. If you want to check whether or not a process is running on another host, there are many ways to approach this problem, and the solution depends on how deep you want to go (or need to go), and what your local situation is. From the top of my head, here are some ideas:

            If you are only dealing with network services with exposed ports:

            • A very simple solution would involve using a script and a port scanner (nmap); if a port that a service is listening behind, is open, then we can assume that the service is running. Run the script every once in a while to check up on the services, and do your thing.

            • If you want to stay in Python, you can achieve the same end result by using Python's socket module to try and connect to a given host and port to determine whether or not the port that a service is listening behind, is open.

            • A Python package or tool for monitoring network services on other hosts like this probably already exists.

            If you want more information and need to go deeper, or you want to check up on local services, your solution will have to involve a local monitor process on each host, and connecting to that process to gather information.

            • You can use your code to implement a server that lets clients connect to it, to check up on the services running on that host. (Check the socket module's official documentation for examples on how to implement clients and servers.)

            Here's the big thing though. Based on your question and how it was asked, I would assume that you do not have the experience nor the insight to implement this in a secure way yet. If you're using this for a simple hobby/student project, roll out your own solution, and learn. Otherwise, I would recommend that you check out an existing solution like Nagios, and follow the security recommendations very closely.



            Differentiate databricks streaming queries in datadog
            Asked 2022-Mar-11 at 18:18

            I am trying to set up a dashboard on Datadog that will show me the streaming metrics for my streaming job. The job itself contains two tasks one task has 2 streaming queries and the other has 4 (Both tasks use the same cluster). I followed the instructions here to install Datadog on the driver node. However when I go to datadog and try to create a dashboard there is no way to differentiate between the 6 different streaming queries so they are all lumped together (none of the tags for the metrics are different per query).



            Answered 2022-Mar-11 at 18:18

            After some digging I found there is an option you can enable via the init script called enable_query_name_tag which is disabled by default as it can cause there to be a ton of tags created when you are not using query names.

            The modification is shown here:



            Ignore specific set of labels on prometheus query
            Asked 2022-Mar-02 at 17:51

            I have a metric with 2 labels. Both labels can have 2 values A or B.

            I'd like to sum all the values and exclude the case when Label1=A and Label2=B.

            I'm trying to set up Prometheus-to-Prometheus metrics flow, I was able to do it by flag --enable-feature=remote-write-receiver.

            However I need to have mTLS there, can someone advice a manual or post a config sample?

            Appreciate you help



            Answered 2022-Feb-24 at 06:08

            There is a second config file with experimental options related to HTTP server, and it has options to enable TLS:



            Prometheus service discovery with docker-compose
            Asked 2022-Feb-19 at 17:59

            I have the following docker-compose file:



            Answered 2022-Feb-19 at 17:59

            The solution to this problem is to use an actual service discovery instead of static targets. This way Prometheus will scrape each replica during each iteration.

            If it is just docker-compose (I mean, not Swarm), you can use DNS service discovery (dns_sd_config) to obtain all IPs belonging to a service:



            Where can I get node exporter metrics description?
            Asked 2022-Feb-10 at 08:34

            I'm new to monitoring the k8s cluster with prometheus, node exporter and so on.

            I want to know that what the metrics exactly mean for though the name of metrics are self descriptive.

            I already checked the github of node exporter, but I got not useful information.

            Where can I get the descriptions of node exporter metrics?




            Answered 2022-Feb-10 at 08:34

            There is a short description along with each of the metrics. You can see them if you open node exporter in browser or just curl http://my-node-exporter:9100/metrics. You will see all the exported metrics and lines with # HELP are the description ones:

            Integrate GCP with OpsGenie for Alerts
            Asked 2022-Jan-26 at 08:39

            It may be a vague question but I couldn't find any documentation regarding the same. Does Google cloud platform have provision to integrate with OpsGenie?

            Basically we have set up few alerts in GCP for our Kubernetes Cluster monitoring and we want them to be feeded to OpsGenie for Automatic call outs in case of high priority incidents.

            Is it possible?



            Answered 2022-Jan-26 at 08:39

            Recapping for better visibility:

            OpsGenie supports multiple tools, including Google Stackdriver.
            Instruction on how to integrate it with Stackdriver webhooks can be found here.

            Install prometheus-metrics-agent

            You can download it from GitHub.
            You can use prometheus-metrics-agent like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the prometheus-metrics-agent component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer For Gradle installation, please refer .


            As the agent works at the bytecode level, we support any language which runs on the JVM. Every language which compiles and runs on the JVM must obey by the bytecode rules. This simply means we need to understand the translation mechanisms of each language for the language level method name to the bytecode level. In Java this is usually 1:1 (excluding some generics fun). You can always examine the javap (the Java Disassembler) command to view the bytecode contents in a more Java centric way. As an example. Lets take the followin Scala class. If we run javap on this. You can do the same for Kotlin, Clojure and any other JVM language. Be aware that there may be some quirks in the naming translations and it may not always be as simple as shown above.
