The secrets MUST be in the following format 17 | 18 | ``` 19 | { 20 | "baseUrl" : "FILL ME WITH THE BASE URL FOR YOUR LOKI OR PROMETHEUS", 21 | "username":"FILL ME WITH THE USERNAME FOR LOKI OR PROMETHEUS", 22 | "apikey":"FILL IN WITH THE API KEY FOR LOKI OR PROMETHEUS" 23 | } 24 | ``` 25 | 26 | Note the secret names from secrets manager under `config/development` at the `LogsSecretName` for Loki and `MetricsSecretName` for Prometheus 27 | 28 | ### Clone the Github Repo that you need to be used as a Knowledgebase for AWS Bedrock 29 | 30 | You **MUST** clone in `assets` folder. 31 | 32 | Few repositories suggested are 33 | 34 | ``` 35 | https://github.com/kubernetes/kube-state-metrics/tree/main/docs/metrics 36 | https://github.com/grafana/loki/tree/main/docs/sources/query 37 | https://github.com/prometheus/node_exporter 38 | https://github.com/google/cadvisor/tree/master/docs 39 | ``` 40 | 41 | ### Enable Bedrock Model Access 42 | 43 | This solution uses `anthropic.claude-3-5-sonnet-20241022-v2:0` and `amazon.titan-embed-text-v1`. Please go to AWS Console>Bedrock>Model Access and enable access to `Claude 3.5 Sonnet V2` and `Titan Embeddings G1 - Textv1.2` 44 | 45 | 46 | ## Deploy Commands 47 | 48 | * Bootstrap CDK Environment - `cdk boostrap` 49 | * Change the mutability of the ECR registry created. If you dont do this then docker push command may fail 50 | * CDK Synth - `cdk synth --context environment=development` 51 | * CDK Deploy - `cdk deploy --context environment=development --all` 52 | * CDK Deploy (no prompt) - `cdk deploy --context environment=development --all --require-approval never` 53 | 54 | Deployment will create the following implementation 55 | 56 | ![image](./images/grafana-genai-asssistant.jpeg) 57 | 58 | ## Post Deployment actions 59 | 60 | * Wait for ~15 minutes for the Knowledgebase web crawler job to finish crawling and indexing the pages in OpenSearch. This is an asynchronous process. You can check this by going to Amazon Bedrock > Knowlede bases > grafana-bedrock-kb-docs > promql-datasource and wait for the Status to be ready. 61 | * To access the UI - Create a user to login in the Cognito Pool and access the load balancer URL in the output. Use the login crendential from the Cognito Pool. Ignore the certificate warning 62 | 63 | ![prompt](./images/prompts.gif) 64 | 65 | 66 | ## Note 67 | 68 | * If you add URLs to crawl in config/development.yaml file, then you must delete the stack `grafana-knowledgebase` (and its dependent stacks) by running `cdk destroy grafana-knowledgebase --context environment=development` and create again by running `cdk deploy --all --context environment=development`. This is because currently, the Custom Resource Lambda function which creates the Bedrock Knowledgebase (`stacks/bedrock_agent/lambda/knowledgebase.py`) doesnt implements any update method. Pull requests are appreciated. 69 | * If you are contributing to this project 70 | * To generate openapi schema required for Bedrock Action group, `cd stacks/roc_action_group/src` and run `docker compose up`. Then go to `http://localhost/openapi.json` to view the generated openapi schema. Save it in the same folder as `openapi_schema.json` -------------------------------------------------------------------------------- /app.py:

You can generate Prometheus Query Language (PromQL) statements and/or Log Query Language (LogQL) based on the intent and context from the user, invoke the generated PromQL or LogQL and interpret the results. 2 | If the user asks anything other than this, then you politely deny. 3 | You first need to identify if you need to query Logs data or metrics data or both based on user's intent and context.Ask the user clarifying questions to capture necessary inputs, specially, if you cannot interpret the kubernetes cluster name. 4 | If you identify you need to query metrics using PromQL 5 | - you first need to get the list of all the available metric names. 6 | - then based on response, you identify, which metrics corresponds to the question that the user asked for. 7 | - You then get a list of available labels that can be used in PromQL statement. 8 | - You then generate simple or complex PromQL statements based on the relevant metrics and filter labels . 9 | - You then invoke the PromQL statement. 10 | If you identify you need to query logs using LogQL 11 | - You first get a list of available labels that can be used in LogQL statement. 12 | - You then generate simple or complex LogQL statements based on the relevant filter labels . Always prefer to generate multiple simple LogQL statements over complex. Do not use any line format expressions such as logfmt or any label format expressions. 13 | - You then invoke the LogQL statement. 14 | Remove any backslash or any escape characters from the generated promql or logql statements. 15 | Instead of running complex promql or logql statements, you should break down in simple statements. 16 | For example, if the promql statement is kube_pod_info{cluster=\"kong31\", namespace=\"grafana-cloud\"}, remove all backslash, so that the promql statement becomes kube_pod_info{cluster="kong31", namespace="grafana-cloud"} . 17 | Ensure the PromQL or logql statement is formatted correctly and does not contain any syntax errors. 18 | Analyze the response received from the API call to summarize your response back to the user. 19 | Render the input to the large language model as a distilled list of succinct statements, assertions, associations, concepts, analogies, and metaphors. The idea is to capture as much, conceptually, as possible but with as few words as possible. 20 | Write it in a way that makes sense to you, as the future audience will be another language model, not a human. 21 | Also, if the response received from the API call is over 100000 tokens then you break down the input that you send to large langugage model in smaller chunks and ask the large langugage model to store all the chunks in its temporary memory and once all the 22 | chunks have been received by the large langugage model, you then ask it to generate a final response back. 23 | Your response back to user should include your analysis from response/output. 24 | Use the available knowledgebase to understand how PromQL statements or LogQL statements should be constructed. 25 | In the last line of your response, mention the generated PromQL statements or LogQL statements, surrounded by tag. 26 | -------------------------------------------------------------------------------- /stacks/bedrock_agent/lambda/knowledgebase.py: -------------------------------------------------------------------------------- 1 | from requests import request 2 | import json 3 | import os 4 | import boto3 5 | import botocore 6 | 7 | session_config = botocore.config.Config( 8 | user_agent_extra=f'APN/1.0 Grafana/1.0 Observability Assistant/168813752b3fd8f8a0e9411b7f9598a683f9854f' 9 | ) 10 | client = boto3.client('bedrock-agent', config=session_config) 11 | #
