            Remove a part of a log in Loki
            Asked 2022-Mar-21 at 10:18

            I have installed Grafana, Loki, Promtail and Prometheus with the grafana/loki-stack.

            I also have Nginx set up with the Nginx helm chart.

            Promtail is ingesting logs fine into Loki, but I want to customise the way my logs look. Specifically I want to remove a part of the log because it creates errors when trying to parse it with either logfmt or json (Error: LogfmtParserErr and Error: JsonParserErr respectively).

            The logs look like this:



            Answered 2022-Feb-21 at 17:57

            Promtail should be configured to replace the string with the replace stage.

            Here is a sample config that removes the stdout F part of the log for all logs coming from the namespace ingress.



            How can you integrate grafana with Google Cloud SQL
            Asked 2022-Mar-21 at 05:50

            I haven't been able to find how to take a Postgres instance on Google Cloud SQL (on GCP) and hook it up to a grafana dashboard to visualize the data that is in the DB. Is there an accepted easy way to do this? I'm a complete newbie to grafana and have limited experience with GCP(used cloud sql proxy to connect to a postgres instance)



            Answered 2022-Mar-20 at 18:50

            Grafana display the data. Google Cloud Monitoring store the data to display. So, you have to make a link between both.

            And boom, magically, a plug-in exists!

            Note: when you know what you search, it's easier to find it. Understand your architecture to reach the next level!



            Enable use of images from the local library on Kubernetes

            Answered 2022-Mar-16 at 08:10

            If your image has a latest tag, the Pod's ImagePullPolicy will be automatically set to Always. Each time the pod is created, Kubernetes tries to pull the newest image.

            Try not tagging the image as latest or manually setting the Pod's ImagePullPolicy to Never. If you're using static manifest to create a Pod, the setting will be like the following:



            Understanding the CPU Busy Prometheus query
            Asked 2022-Mar-19 at 12:37

            I am new to Grafana and Prometheus. I have read a lot of documentation and now I"m trying to work backwards by reviewing some existing queries and making sure I understand them

            I have downloaded the Node Exporter Full dashboard ( I have been reviewing the CPU Busy query and I"m a bit confused. I am quoting it below, spaced out so we can see the nested sections better:

            In this query, job is node-exporter while instance is the IP and port of the server. This is my base understanding of the query: node_cpu_seconds_total is a counter of the number of seconds the CPU took at a given sample.

            1. Line 5: Get cpu seconds at a given instant, broken down by the individual CPU cores
            2. Line 4: Add up all CPU seconds across all cores
            3. Line 3: Why is there an additional count()? Does it do anything?
            4. Line 12: Rate vector - get cpu seconds of when the cpu was idle over the given rate period
            5. Line 11: Take a rate to transfer that into the rate of change of cpu seconds (and return an instant vector)
            6. Line 10: Sum up all rates, broken down by CPU modes
            7. Line 9: Take the single average rate across all CPU mode rates
            8. Line 8: Subtract the average rate of change (Line 9) from total CPU seconds (Line 3)
            9. Line 16: Multiple by 100 to convert minutes to seconds 10: Line 18-20: Divide Line 19 by the count of the count of all CPU seconds across all CPUs

            My questions are as follows:

            • I would have thought that CPU usage would simply be (all non idle cpu usage) / (total cpu usage). I therefore don't understand why take into account rate at all (#6 and #8)
            • The numerator here seems to be trying to get all non-idle usage and does so by getting the full sum and subtracting the idle time. But why does one use count and the other sum?
            • If we grab cpu seconds by filtering by mode=idle, then does adding the by (mode) add anything? There is only one mode anyways? My understanding of by (something) is more relevant when there are multiple values and we group the values by that category (as we do by cpu in this query)
            • Lastly, as mentioned in bold above, what is with the double count(), in the numerator and denominator?


            Answered 2022-Mar-19 at 12:37

            Both of these count functions return the amount of CPU cores. If you take them out of this long query and execute, it'll immediately make sense:



            Thanos-Query/Query-Frontend does not show any metrics
            Asked 2022-Feb-24 at 15:46

            Basically, I had installed Prometheues-Grafana from the kube-prometheus-stack using the provided helm chart repo prometheus-community



            Answered 2022-Feb-24 at 15:46

            It's not enough to simply install them, you need to integrate prometheus with thanos.

            Below I'll describe all steps you need to perform to get the result.

            First short theory. The most common approach to integrate them is to use thanos sidecar container for prometheus pod. You can read more here.

            How this is done:

            (considering that installation is clean, it can be easily deleted and reinstalled from the scratch).

            1. Get thanos sidecar added to the prometheus pod.

            Pull kube-prometheus-stack chart:

            There are many agents capable of saving metrics collected in k8s to remote Prometheus server outside the cluster, example Prometheus itself now support agent mode, exporter from Opentelemetry, or using managed Prometheus etc.

            I'm trying to use azure monitor as a data source for grafana. The grafana server was created from Azure Marketplace. I used Service Principal for authentication and while clicking the 'save and test' button, I get the following error"

            ' 1. Successfully queried the Azure Monitor service. 2. Workspace not found. '

            Can you please help me with this issue? Thank you.

            Adding a Azure App Insights resource to the monitored Subscription solved the problem. On this step the first Monitoring Workspace for the Subscription was created. On an older Resource I had to migrate to Workspace-based Application Insights to fix the error. It seams Grafana only works with the new Workspace-based Application Insights resources

            PostgreSQL Default Result Limit
            Asked 2022-Jan-01 at 15:34

            I'm using Grafana and PostgreSQL 13 for visualizing. There are many users in the Grafana and they could send queries to their own databases.

            I need to set a default result limit for sent queries. (Like 1000) But I couldn't find a solution. I analyzed the PgPool to rewrite the query but I think it couldn't do that.

            Is there any solution for that? I'm not sure but maybe I need a TCP Proxy which can do.



            Answered 2022-Jan-01 at 15:34

            The most popular solution, as far as I know, is PgBouncer. PgBouncer is a lightweight connection pooler for PostgreSQL. It acts as a Postgres server, so simply point your Grafana and other clients to the PgBouncer port.

            Here are some installation guides for Linux (Ubuntu, Debian, CentOS):



            Trigger Beam ParDo at window closing only
            Asked 2021-Dec-15 at 18:24

            I have a pipeline that read events from Kafka. I want to count and log the event count only when the window closes. By doing this I will only have one output log per Kafka partition/shard on each window. I use a timestamp in the header which I truncate to the hour to create a collection of hourly timestamps. I group the timestamps by hour and I log the hourly timestamp and count. This log will be sent to Grafana to create a dashboard with the counts.

            Below is how I fetch the data from Kafka and where it defines the window duration:



            Answered 2021-Dec-15 at 18:24

            You can use the trigger “Window.ClosingBehavior”. You need to specify under which conditions a final pane will be created when a window is permanently closed. You can use these options:

            • FIRE_ALWAYS: Always Fire the last Pane.

            • FIRE_IF_NON_EMPTY: Only Fire the last pane if there is new data since previous firing.

            You can see this example.
