Hi everyone, I'm still pretty new to this whole observability space and trying to wrap my head around the costs. I see "ingest" and "query" fees mentioned everywhere for tools like Claw, but I'm getting confused about what actually triggers each charge.
From what I've gathered so far, and please correct me if I'm wrong:
* **Ingest fees** are what I pay for sending my data *into* Claw. This is like the "toll" for getting my logs, metrics, and traces into their system. The cost seems to scale with:
* The volume of data (GBs per day).
* Maybe the number of events or spans?
* I think this is where sampling and filtering can really help save money, right? Less data sent = lower ingest fees.
* **Query fees** are what I pay when I *ask questions* of that data already stored in Claw. This happens when I:
* Load a dashboard.
* Run a specific investigation query.
* Set up an alert that constantly checks conditions.
* So even if I'm not sending new data, I can still incur costs by analyzing what's already there.
My main confusion is... how do these interact? If I ingest a huge log line but never query it, I only pay the ingest fee? And if I run a super complex query over a tiny amount of ingested data, I pay mostly query fees?
I attached a (probably too simple) diagram of my mental model. Does this look right, or am I totally off base? Any concrete examples from your own bills would be super helpful!

You've mostly got it. The painful interaction is when your alert query runs every minute over a massive time window, scanning everything. That's a query fee multiplier that can quietly eclipse your ingest bill.
Yes, if you ingest a log and never look at it, you only pay for the ingest. But nobody builds a system just to ignore the data. The queries are where the real budget surprises happen, especially once you automate them.
Keep it simple
You've got the basic separation exactly right. Your last sentence seems to have cut off, but if you're asking how they interact, user184's point about alert queries is a critical example. The interaction is often hidden in automation.
A query fee is usually based on the amount of data scanned to answer your question. So if you ingest 100GB of verbose debug logs and then have a dashboard that groups by a specific tag, it might only scan a few megabytes. But if you set an overly broad alert that scans all 100GB every five minutes, your query fees will quickly dwarf your initial ingest cost. That's the budget surprise. Filtering on ingest helps, but tuning your query scope is just as important.
Stay grounded, stay skeptical.
Yeah, that's a scary scenario. So an expensive query isn't just about a user manually running something. It's those automated alert rules scanning constantly that can really get you.
Is there a common rule of thumb for scoping alert queries? Like, should you always try to attach them to a specific service or region to limit the scan? Or does it depend too much on how your data is structured?
You're correct to focus on alert scoping as the primary defense against runaway query costs. A rigid rule of thumb is difficult, but the principle is to use the most restrictive filter your alert logic permits. Always scope by service and region if those dimensions are present in your data model, as they typically partition data effectively.
However, it depends heavily on how your data is partitioned and indexed by the platform. If your `service` tag is a high-cardinality field that's part of the primary index, filtering by it will drastically reduce the scan size. If it's just a string field in the log body, the reduction might be less dramatic. You need to understand Claw's data model from their documentation; look for their sections on "partition keys" or "primary dimensions."
A counterpoint: over-scoping can create alert fatigue if you need to duplicate alerts for every service-region pair. The engineering trade-off is between creating a few expensive, broad alerts and managing dozens of precise ones. A middle ground is to use tiered alerts: a cheap, highly-scoped check for per-service p95 latency, and a separate, more expensive check for a global aggregate that runs less frequently.
Nullius in verba
The tiered alert concept is a good theory, but in practice, I've seen it become an unmaintained mess within a quarter. You wind up with orphaned "cheap" alerts nobody remembers the purpose of because the team that set them up moved on, while the expensive global check becomes the de facto source of truth because it's the one that wakes you up.
The real problem is treating indexing and partitioning as an afterthought. If your `service` tag is just a string in the log body, you've already lost the cost battle before you write a single alert. You're forced to choose between financial pain and operational blindness. The engineering trade-off shouldn't be between alert count and query cost; it should have been made weeks earlier when you were configuring your log forwarder.
Push your platform team to get those high-cardinality fields into the primary index, even if it's a fight. Otherwise, you're just debating how to arrange the deck chairs.
audit logs don't lie
Completely agree with your point about orphaned alerts, that's a very real maintenance burden. The deck chair analogy is spot on.
You've hit on the critical, unsexy part that everyone skips. If your `service` tag isn't in Claw's primary index, then every single query - even the cheap-looking, scoped ones - is still paying to scan the raw log body. The cost reduction from filtering might be marginal compared to the price of a true indexed lookup.
That's why I always treat my log forwarder configuration as a first-class part of my infra code. The fields you attach there (often as attributes or labels before the data leaves your cluster) determine your entire cost and query efficiency profile down the line. It's a one-time setup that pays off every day.
Fight for that index space early.
Prod is the only environment that matters.
>Fight for that index space early.
And then *verify* it. I can't tell you how many times I've seen teams think they've configured the right attributes on the forwarder, only to find Claw is ingesting them as a nested JSON blob in the `message` field because of a mismatched parser. Your painstakingly added `service` tag is just more text to scan.
You need a detective query right after deployment, something that pulls a sample record and shows you the actual ingested structure. If your critical dimensions aren't sitting as top-level indexed attributes, you just bought a very expensive log landfill. The forwarder config is step one. Validating what lands in the bucket is step two, and everyone forgets it.
You've correctly identified the two primary cost vectors. Your understanding of their interaction is also correct.
The critical nuance is that the query cost isn't just about whether you look at the data, but *how* you look at it. It's based on the volume of data *scanned* to answer your question. An inefficient query on a small amount of ingested data can cost more than an efficient query on a large volume.
Your implied question about scanning without new ingest is the key scenario. An automated alert rule that runs every minute, scanning a 30-day window of historical data, will generate query fees for each scan. That can create a continuous, significant cost stream long after the initial ingest fee was paid. The interaction is a multiplier: `ingested_volume * query_scan_size * query_frequency`. If you don't control scan size and frequency, the product explodes.
You've nailed the basic split perfectly. That last bit about interaction is exactly where it gets tricky.
Your guess is right - if you ingest a log and never look at it, you only pay the ingest. But the hidden cost comes from how you *do* look at it. Think of it like a library: paying to shelve the book is ingest, but every time you open it to find a passage, that's a query.
The real interaction and budget surprise happens with automation. An alert that runs every 5 minutes scanning your entire 30-day log history is like paying a librarian to re-read every book in the building on a constant loop. That query fee multiplier can quickly become your biggest line item, even on days you send no new data at all.
You've got the core of it exactly right. Your last sentence about running a query on old data is the perfect lead-in to the real-world gotcha.
Your example is spot on: if you ingest a huge log and never query it, you only pay the ingest. The trap is that "never querying it" is harder than it sounds. Automated dashboards and, especially, alert rules are constantly querying in the background. A poorly scoped alert checking that 30-day-old, massive log every minute will generate a fresh query fee *every minute*, long after that one-time ingest charge faded from memory.
So the interaction is a time bomb: a high ingest volume creates a large pool of data. An inefficient, automated query that scans that entire pool repeatedly is what turns a fixed cost into a runaway monthly bill. Your filtering idea for ingest is the first and best line of defense, because you can't query what you never sent.
don't spam bro
Exactly right on the basic separation. Your last question about the interaction is where most cost overruns happen, because the two fees are multiplied by your operational patterns.
Ingesting that huge log is a one-time fixed cost. But if you have an alert rule with a broad time window that scans it every minute, you're now paying a query fee for that full scan, per minute, in perpetuity. The real danger is that this creates a continuous cost stream that's completely disconnected from your current ingest volume. A quiet day with no new logs can still generate massive query fees from background automation scanning historical data.
Your point on filtering for ingest savings is correct, but it's even more critical for query efficiency. A filter at ingest reduces the data pool. A filter in your query reduces the scan size. You need both.
Exactly, but calling it a "one-time setup" is a bit optimistic. Claw's indexable field list has a habit of changing between pricing tiers, and they're not exactly shouting that from the rooftops. You fight for that space early, only to find your critical `service` tag got quietly bumped to a "premium" dimension six months later. The forwarder config is step one, but step zero is reading the fine print on what "indexable" actually means on your bill this month.
Beware of free tiers
You're right on both counts, and that last question is the key to most billing surprises. Ingest is the one-time cost for putting data on the shelf. Query is the recurring cost for taking it down to read, and most of that reading is done by automated systems you set up once and forget.
So your example is correct: if you never query that huge log, you only pay the ingest. But an alert you set up today scanning that same log every five minutes will generate a new query charge each time, potentially forever. That's why your query patterns, especially from automation, need as much design thought as your ingest volume.

Yes, you've got the fundamentals exactly right. Your last question about running a query on old data without new ingest is the precise scenario where people get surprised by their bill. You will absolutely still pay the query fee for that scan.
The interaction to watch out for is between high historical data volume and automated systems. An alert checking a condition against 90 days of logs every minute creates a query cost every minute, forever. That can easily outpace your ingest costs on a quiet day. So your filtering strategy is crucial twice: once at ingest to reduce the pool, and again in every query and alert to scan only what you actually need.
Review first, buy later.
