AI: LLM Spend Control with LiteLLM Budgets and OpenAI Limits
0 (0)

24 September 2026

The main goal we had when introducing LiteLLM AI Gateway on the project (see LiteLLM: AI Gateway for LLMs – features overview) was access and cost control, because right now we can’t enable auto-recharge for our OpenAI or OpenRouter account: our startup is still in the development and experimentation stage, developers actively use AI agents… Read More: AI: LLM Spend Control with LiteLLM Budgets and OpenAI Limits0… »

LiteLLM: Debugging AI Cost Monitoring with VictoriaMetrics
5 (1)

16 September 2026

Had a pretty interesting case with monitoring LLM costs through LiteLLM when using multiple providers. What we have: LiteLLM: AI Gateway, all our services work through it, it proxies requests to providers, generates metrics and traces, controls access, spending, etc. OpenAI and OpenRouter: currently the two main providers LiteLLM sends requests to some clients (our… Read More: LiteLLM: Debugging AI Cost Monitoring with VictoriaMetrics5 (1) »

VictoriaTraces: Recording Rules, Metrics, and Alerts from Trace Spans
0 (0)

22 May 2026

VictoriaTraces – just like VictoriaLogs – supports Recording Rules (see VictoriaMetrics: Recording Rules for AWS Load Balancer logs) for traces, because traces are essentially the same logs, just structured differently. And since we have Recording Rules – we can build metrics out of logs for alerts and Grafana dashboards. Although this actually isn’t the best… Read More: VictoriaTraces: Recording Rules, Metrics, and Alerts from Trace Spans0 (0) »

VictoriaTraces: Tracing, Observability, and OpenTelemetry
0 (0)

19 May 2026

On the project, we’ve gradually grown to the point where it’s time to have proper tracing – to build real observability, not just monitoring. A long time ago I did something similar with Jaeger – a monster, and it kind of stayed in my drafts from 2019 or 2020. Since right now our entire stack… Read More: VictoriaTraces: Tracing, Observability, and OpenTelemetry0 (0) »

VictoriaMetrics: Basic Monitoring for AWS, Linux, NGINX, and PHP
5 (1)

28 March 2026

The RTFM migration from DigitalOcean to AWS went smoothly, and I’m gradually settling in. New infrastructure, everything new – so for the first while I want to keep a close eye on the server and blog state, which means setting up basic monitoring for WordPress: NGINX, PHP-FPM, the database, and the infrastructure running it all.… Read More: VictoriaMetrics: Basic Monitoring for AWS, Linux, NGINX, and PHP5 (1) »

Okta: Configuring Grafana SSO with OIDC and Role Mapping
5 (1)

27 March 2026

We finally “grew up” to using Okta on the current project, so there’s a short series of posts coming up on it. I wrote about Okta before, but that was 5-6 years ago, and there have been some interesting changes since then (see the #okta tag). Today we’ll be configuring SSO login via Okta for… Read More: Okta: Configuring Grafana SSO with OIDC and Role Mapping5 (1) »

FreeBSD: Home NAS, part 11 – extended monitoring with additional exporters
0 (0)

10 February 2026

In the previous post FreeBSD: Home NAS, part 10 – monitoring with VictoriaMetrics and Grafana, we configured VictoriaMetrics, node_exporter, Grafana and created a basic dashboard and basic alerts. Now, I want to add a bit more monitoring – to see process CPU/RAM data, SMART information, and ZFS details. Everything written here has been added to… Read More: FreeBSD: Home NAS, part 11 – extended monitoring with additional… »

FreeBSD: Home NAS, part 10 – monitoring with VictoriaMetrics and Grafana
3.8 (6)

7 February 2026

Finally got around to monitoring. I was interested in running a standard stack with VictoriaMetrics + Grafana + Alertmanager not in the usual Kubernetes with a Helm chart, but simply on the host. However, the approach is the same as monitoring services in AWS/Kubernetes – on FreeBSD, we will have VictoriaMetrics for metrics, Grafana for… Read More: FreeBSD: Home NAS, part 10 – monitoring with VictoriaMetrics and… »

Kubernetes: monitoring processes with process-exporter
0 (0)

1 November 2025

We are debugging one issue with memory usage in Kubernetes Pods, and decided to look at the memory and number of processes on the nodes. The problem is that a Kubernetes Pod with Livekit usually consumes about 2 gigabytes of memory, but sometimes there are spikes of up to 10-11 gigabytes, which causes the Pod… Read More: Kubernetes: monitoring processes with process-exporter0 (0) »

AWS: Monitoring AWS OpenSearch Service cluster with CloudWatch

1 November 2025

Let’s continue our journey with AWS OpenSearch Service. What we have is a small AWS OpenSearch Service cluster with three data nodes, used as a vector store for AWS Bedrock Knowledge Bases.
