Telemetry streaming to Elasticsearch
Hi all I am following a couple of threads since I want to send ASM logging to Elasticsearch like this one fromGreg What I understand is that I need to send an AS3 declaration and a TS declaration. But there are a couple of things not entirely clear to me. 1. Can I remove the iRule, Service_TCP, Pool, Log_Destination, Log_Publisher and Traffic_Log_profile declarations from the AS3 declaration json? In the example the telemetry_asm_security_log_profile does not seem to depend on these? 2. In the AS declaration json an IP address is specified 255.255.255.254 (perhaps just an example since it is a subnet mask) and also in the TS declaration where it is 172.16.60.194. How are the IP in the servers section of the AS3 declaration related to the one in the consumer part in the TS declaration? 3. Intelemetry_asm_security_log_profile the field remoteStorage is set to splunk. According to the reference guide:Reference Guide security-log-profile-application-objectthe allowed values are “remote”, “splunk”, “arcsight”, “bigiq”. I would opt for just remote. Is that the correct choice? Regards HansStreaming Telemetry Errors to Kafka

Automation Toolchain - Telemetry Streaming - Grafana StatsD Graphite
Introduction This article explains how to use the Telemetry Streaming component (TS) of the Automation Tool chain (ATC) for integration with Grafana through StatsD and Graphite. To get more information on the Push Consumer supported by the F5 Networks ATC, more in particular the TS component, please refer to the official documentation on CloudDocs here. BIG-IP Configuration In order to configure the TS component of the ATC correctly for integration with Grafana, we will need to post the following JSON blob to your BIG-IP TS API endpoint at https://<BIG-IP-ADDRESS>:8443/mgmt/shared/telemetry/declare { "class": "Telemetry", "MyTelemetrySystem": { "class": "Telemetry_System", "allowSelfSignedCert": true, "systemPoller": { "interval": 60 } }, "GraphiteConsumer": { "class": "Telemetry_Consumer", "type": "Graphite", "host": "10.0.0.55", "protocol": "http", "port": 80 }, "StatsdConsumer": { "class": "Telemetry_Consumer", "type": "Statsd", "host":"10.0.0.55", "protocol": "udp", "port": 8125 }, "MyTelemetryListener": { "class": "Telemetry_Listener", "port": 6514 } } The above 4 JSON stanzas are the following A Telemetry System class, that sets up the system poller. More information here. Two Push Consumers classes, that will push the metrics or data externally. In this case to Graphite and StatsD. More information here. A Telemetry Listener class, that sets an Event Listener )both TCP and UDP protocols) and can accept events in a specific format and process them. More information here Note that in this example, Graphite and StatsD are running on the same host, because we used a docker container to host them as follows # docker run -d \ --name graphite \ --restart=always \ -p 80:80 \ -p 2003-2004:2003-2004 \ -p 2023-2024:2023-2024 \ -p 8125:8125/udp \ -p 8126:8126 \ graphiteapp/graphite-statsd Telemetry data Let's have a look at the TS telemetry data being produced and send over to Graphite. StatsD is used for metrics, Graphite is being used for events StatsD metrics StatsD is supporting 3 main metric types: gauges, timers and counters. The TS StatsD integration is using Gauges. We can use Netcat to have a look at the format of these gauge based metrics # echo "gauges" | nc 10.0.0.55 8126 { 'statsd.timestamp_lag': 0, 'f5telemetry.ip-10-0-0-130-eu-west-1-compute-internal.system.networkInterfaces.1-0.counters-bitsIn': 297895992, 'f5telemetry.ip-10-0-0-130-eu-west-1-compute-internal.system.networkInterfaces.1-0.counters-bitsOut': 0, 'f5telemetry.ip-10-0-0-130-eu-west-1-compute-internal.system.networkInterfaces.mgmt.counters-bitsIn': 248764520, 'f5telemetry.ip-10-0-0-130-eu-west-1-compute-internal.system.networkInterfaces.mgmt.counters-bitsOut': 134973160, 'f5telemetry.ip-10-0-0-130-eu-west-1-compute-internal.system.tmmTraffic.clientSideTraffic-bitsIn': 62854192, 'f5telemetry.ip-10-0-0-130-eu-west-1-compute-internal.system.tmmTraffic.clientSideTraffic-bitsOut': 229153456, 'f5telemetry.ip-10-0-0-130-eu-west-1-compute-internal.system.tmmTraffic.serverSideTraffic-bitsIn': 62432120, 'f5telemetry.ip-10-0-0-130-eu-west-1-compute-internal.system.tmmTraffic.serverSideTraffic-bitsOut': 228977008, ... We can also see the same gauge metrics inside the Graphite admin UI The structure and path of this telemetry data is important when you create you own dashboards Graphite events As mentioned earlier, the TS Graphite integration uses events to send the data to Graphite. You can observe those events by going to the /events endpoint on your Graphite admin UI The details of such an event are as follows Grafana In order to be able to use and display the data now collected in Graphite, one needs to set-up Graphite as a data source and import a Grafana dashboard that uses this data Graphite data source Let's add Graphite as a data source Grafana BIG-IP TS dashboard Let's import an example dashboard that used the data available. This sample dashboard is also available in the Grafana dashboard collection online here This sample dashboard will make use of dashboard variables, so users can filter on parameters like Device (which BIG-IP), Tenant (which BIG-IP partition), Application, Virtual Server and Pool. For the sake of demonstration, there is also a filter for Profile For more information and screenshots on the dashboard itself, refer to the Grafana website where the dashboard is downloadable. The dashboard contains separate rows for application health status: 4xx and 5xx responses. You can add slow responses as well as a matter of excercise device system statistics: CPU, memory, TTM traffic in/out, interface traffic in/out virtual server traffic in/out and server connections pool traffic in/out and server connections members traffic in/out and server connections profile details statistics The variable queries used for this dashboard are as follows, based on the structure of the metrics data you will find in the Graphite admin UI Conclusion In this article we have demonstrated how the F5 Automation Tool Chain, and more in particular also its Telemetry Streaming component, is a perfect match for integration into popular DevOps telemetry solutions. For a fully automated scenario, demonstrating the usage of Declarative Onboarding (DO), Application Services 3 (AS3) and Telemetry Streaming (TS) with automated Grafana integration, you can refer to the following Github repo.
Prometheus and basic auth
Dear all I have setup telemetry streaming so that a remote prometheus server can scrape metrics. I used this advice to use a guest account for "basic auth" done on prometheus : https://devcentral.f5.com/s/articles/icontrol-rest-fine-grained-role-based-access-control-30773 Here is the prometheus scrape_configs entry : - job_name: bigip honor_timestamps: true scrape_interval: 10s scrape_timeout: 10s metrics_path: /mgmt/shared/telemetry/pullconsumer/My_Prometheus scheme: https basic_auth: username: prometheus password: <secret> tls_config: ca_file: /etc/ssl/certs/ca.crt cert_file: /etc/ssl/certs/prometheus.crt key_file: /etc/ssl/certs/prometheus.key insecure_skip_verify: false static_configs: - targets: - lb5 My problem is excessive warning messages in the logs : Dec 13 16:33:37 lb5 warning httpd[13888]: [warn] [client XXXX] AUTHCACHE Error processing cookie 7BA470C4F1E2F722E1685046756D1F1A70621E38 - Cookie user mismatch The problem is clearly identified (K11140735) but changing pam idle timeout is not a solution as promtheus scrapes every 10s which is too low for an usual webui idle timeout. I was wondering if there is a fix or other way to do it ? Using a F5 token is not a solution as prometheus does not seam to support it in its scrape_config section (https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config). Thanks for your help ;-))
Telemetry streaming - One click deploy using Ansible
In this article we will focus on using Ansible to enable and install telemetry streaming (TS) and associated dependencies. Telemetry streaming The F5 BIG-IP is a full proxy architecture, which essentially means that the BIG-IP LTM completely understands the end-to-end connection, enabling it to be an endpoint and originator of client and server side connections. This empowers the BIG-IP to have traffic statistics from the client to the BIG-IP and from the BIG-IP to the server giving the user the entire view of their network statistics. To gain meaningful insight, you must be able to gather your data and statistics (telemetry) into a useful place.Telemetry streaming is an extension designed to declaratively aggregate, normalize, and forward statistics and events from the BIG-IP to a consumer application. You can earn more about telemetry streaming here, but let's get to Ansible. Enable and Install using Ansible The Ansible playbook below performs the following tasks Grab the latest Application Services 3 (AS) and Telemetry Streaming (TS) versions Download the AS3 and TS packages and install them on BIG-IP using a role Deploy AS3 and TS declarations on BIG-IP using a role from Ansible galaxy If AVR logs are needed for TS then provision the BIG-IP AVR module and configure AVR to point to TS Prerequisites Supported on BIG-IP 14.1+ version If AVR is required to be configured make sure there is enough memory for the module to be enabled along with all the other BIG-IP modules that are provisioned in your environment The TS data is being pushed to Azure log analytics (modify it to use your own consumer). If azure logs are being used then change your TS json file with the correct workspace ID and sharedkey Ansible is installed on the host from where the scripts are run Following files are present in the directory Variable file (vars.yml) TS poller and listener setup (ts_poller_and_listener_setup.declaration.json) Declare logging profile (as3_ts_setup_declaration.json) Ansible playbook (ts_workflow.yml) Get started Download the following roles from ansible galaxy. ansible-galaxy install f5devcentral.f5app_services_package --force This role performs a series of steps needed to download and install RPM packages on the BIG-IP that are a part of F5 automation toolchain. Read through the prerequisites for the role before installing it. ansible-galaxy install f5devcentral.atc_deploy --force This role deploys the declaration using the RPM package installed above. Read through the prerequisites for the role before installing it. By default, roles get installed into the /etc/ansible/role directory. Next copy the below contents into a file named vars.yml.

Need help extracting fields from Telemetry streamed JSON in Splunk
Hi, We are streaming telemetry data from an F5 into Splunk, specifically client side bits in and out for all virtual servers. That part is working. In Splunk however I cannot extract or reference the field to get to the metrics. I've tried various arrangements of spath (index="f5_ltm"| spath "virtualServers{}.clientSide.bitsIn" output=n | table n) but none yield any data from the search. Any help or pointer is greatly appreciated. Thank you.
