# Time Series Billing

**custom metrics**through a flexible and cost-effective Time Series Billing model aligned with your usage. With an enhanced billing experience, you can view your time-series consumption at a glance, analyze trends, and change subscription plans if need be.

Use the Sysdig **Subscription** page to view your account licensing, usage,
and spending. Based on your current subscription tier, time-series usage,
and the number of active agents, you can estimate your Sysdig time series
consumption costs and take further actions. Time Series Billing works only
in SaaS environments and is not currently available in on-prem environments.

See How Time Series Databases Work to learn more about time series and how promQL works with time series.

## Benefits of Time Series Billing

Flexible time series billing allows you to consume as much time series as is necessary for your environment. Time series billing is applicable to “custom” time series, ingested via the following means:

Custom time series ingested through the Sysdig agent

- Including time series ingested from applications Monitoring Integrations, for example NGINX and Redis.

Custom time series ingested via other Prometheus servers through Prometheus Remote Write.

Custom time series ingested via Cloud Integrations (cloud platform metrics).

See Use Cases for more details.

For more information understanding and controlling metric usage, including dropping time series that is not required see Control Time Series Ingestion.

## Billing Custom Time Series

Sysdig calculates the time series ingestion overage price in the following way:

- Total custom time series consumption is metered for each hour.
- The consumption is compared against the custom time series entitlement for that hour, based on the subscription.
- The custom time series ingestion overage for the hour is calculated as the difference between the total hourly consumption and the entitlement.
- Each calendar month’s bill is calculated based on the
**95th percentile of all hourly time series ingestion overages during that month**.

## Consuming Custom Time Series

Sysdig meters the following types of custom metrics ingested by the Sysdig agent:

- Prometheus (including Monitor Integrations and custom Prometheus jobs)
- JMX
- App Checks
- statsd

In addition, all metrics and metadata ingested via Prometheus Remote Write and cloud platform metrics are metered against custom time series.

Metrics which do not fall into one of the above categories, such Kube State Metrics (KSM) and container metrics, are not considered custom metrics and thus not counted against custom time series entitlements.

### Time Series Entitlement

Custom time series consumption is calculated against the reserved time series included as an entitlement with your subscription. The basic Sysdig Monitor plan includes a 2,000 time series entitlement per agent per hour. You can purchase more by adding on-demand agents or time series packs.

Reserved time series is the number of custom time series per hour, a user is entitled to via
the Sysdig subscription. The total value of entitled time series per
account (for each hour) is calculated as `(the number of reserved agents + the number of connected on-demand agents during that hour) * the number of time series per agent`

.

Time series consumed beyond your subscription entitlement is aggregated across all agents running in your environment. For example, if you have two agents running, you can consume 3,000 metrics on one agent and 1,000 on another, for a total of 4,000 TS, without incurring additional charges (based on the default entitlement of 2,000 TS per agent).

The default time series entitlement of 2,000 time series is applicable only to custom metrics. Metrics which do not fall into the custom metric category, such Kube State Metrics (KSM) and container metrics, are not considered custom metrics and thus not counted against custom time series entitlements.

#### Time Series Entitlement Example

Let’s assume that your Sysdig Monitor subscription includes 15 total Sysdig
reserved agents. Each one of those agents is entitled to 2,000 custom time series
per hour. To determine the total maximum time series for an account,
multiply the number of agents by the time series entitlement per agent –
`15 * 2,000 = 30,000`

– which means that the account is entitled to consume
30,000 custom time series per hour aggregated across all agents. Any one agent can consume
greater than the 2,000 entitlement as long as the maximum for all agents
does not exceed the account entitlements (in this example, 30,000).

Any time series consumed beyond your entitlement will be charged an overage charge. Additional time series packs can be purchased to increase your overall maximum time series entitlement.

Contact Sales to purchase time series packs to extend your subscription entitlement.

### Time Series Packs

Time series packs are available to purchase to increase your custom time series entitlements per Account. A time series pack includes 1,000 time series and is charged per month.

Using the above example, if you purchase **ten time series packs** consisting of
1,000 time series per pack, you will increase the default time series in
your account from 30,000 to 40,000. This will entitle you to consume 10,000
more metrics across all of the Sysdig agents.

## Monitor Time Series Usage

### Time Series Metrics

To help you identify the usage trends that are important to you, Sysdig provides the following metrics via the Time Series Dashboard:

`sysdig_ts_usage`

: The metric reports the number of time series ingested for a user in a 20-minutes interval. The dashboard reports the 1-hour usage, which is the maximum of the three 20-minute`sysdig_ts_usage`

measurements taken in an hour. This metric can be segmented on metric categories as well.`sysdig_ts_usage_10s`

: The metric reports the number of time series ingested for a user in every 10-seconds window, per host (agent), and per metric category.

### Download Usage

You can download the usage report in a CSV file. On the **Subscription**
page, under **Subscription Details**, click **Download Usage** to
download a copy of the usage report. You can view the following:

User ID

Time

Number of Reserved Agents

Number of Connected On-Demand Agents

Time Series included per agent

### Time Series Usage Dashboard

Sysdig provides a Time Series Usage Dashboard with insight into the usage data. You can view time series ingestion at a glance to discover and analyze trends on where time series is coming from. The dashboard shows the total number of time series; top hosts by time series ingestion, current ingestion rate; churn percentage; and so on.

### Access the Time Series Dashboard

On the **Subscription** page, under **Usage**, click **Time Series Dashboard**. You can view the following:

- Current 1 Hour Ingestion
- Current Ingestion from Agents
- Churn Percentage
- The average number of time series per host
- The number of time series ingested per category
- Host-level ingestion

## Calculate Time Series Usage

Time series usage is calculated by using the `sysdig_ts_usage`

metric.
The metric reports the number of time series ingested for a user in an hour
(sum of the maximum of three 20-minutes). For each hour, the number of time
series ingested is calculated, and then the value is deducted from the
number of reserved time series. This value is stored as the usage record.

An hour period is considered in order to take the
churn
into account. Sysdig uses the `sysdig_ts_usage_10s`

metric to calculate
the spikes caused by
churns
and provides you the churn percentage in the dashboard.

Sysdig uses the 95th percentile to calculate the exceeding cost of usage. At the end of the month, the 95th percentile of the total number of active series ingested per hour is calculated. Calculating the 95th percentile reduces the chances of billing you for unexpected spikes causes by churns.

### Churn Rate

When a time series stops receiving new data points, it becomes inactive. This event is called time series churn. It occurs more often during an upgrade in a Kubernetes cluster or when containers are replaced by new ones. Restarts, redeploys, dynamic workloads also cause churn and generate additional time series.

For example, in such cases the `container_id`

label in a container metric changes, and
subsequently, all the existing time series are replaced by new time series
(with the new `container_id`

value).

The churn rate is the number of time series that churn over time. Sysdig
uses the `sysdig_ts_usage_10s`

metric to analyze these scenarios.

The Time Series Usage Dashboard provides a ratio of time series detected at 1-hour period and 10-seconds period. This ratio is known as the churn percentage and it is expressed as this PromQL query:

`(sum(sysdig_ts_usage{metric_category!='PROMETHEUS_REMOTE_WRITE'}) - sum(sysdig_ts_usage_10s)) / sum(sysdig_ts_usage{metric_category!='PROMETHEUS_REMOTE_WRITE'}) * 100`

Time series collected by Prometheus Remote Write are excluded from this ratio because they are not collected by the Sysdig agent.

### Time Series Billing Example

Time series billing is calculated per month. A basic subscription will provide you 2,000 time series per agent. This entitlement is applicable only to custom metrics, while you can continue consuming Sysdig and KSM metrics without incurring additional costs. Time series consumed beyond your subscription limit will be charged and is aggregated across all agents running in your environment.

For example, if you have three agents running in your environment with the following consumption details:

- Entitled number of time series per hour (reserved agents * 2,000): 3 * 2,000 = 6,000
- Actual time series consumed by all agents = 7000
- Any overage is calculated by subtracting the total entitlement value from
the actual consumption value, in this case
`(7,000 - 6,000) = 1,000`

. This account would be charged over overage of 1,000 time series.

## Use Cases

### On-Demand Time Series Consumption

Let’s say you have a Sysdig Monitor account which primarily consumes metrics from downstream Prometheus servers via Prometheus Remote Write. As such, you have only licensed the account for one Sysdig Agent, which entitles your account to 2,000 time series.

Assuming the following volume examples:

- Two Prometheus Servers sending metrics to Sysdig via Remote Write
- Prometheus Server 1 generates
`50,000`

time series consistently every hour during a month - Prometheus Server 2 generates
`150,000`

time series consistently every hour during a month - One Sysdig agent which collects
`1,000`

time series consistently every hour during a month

The time series billing for the month is calculated as follows:

- Time series usage is the same for every hour: Total custom time series consumed - Subscription entitlement
`(50,000 + 150,000 + 1,000) - 2,000 = 199,000`

On-demand time series pricing is measured in blocks of 1,000 time series per month. To determine the amount of on-demand time series you will be billed for, divide the total time series usage from the above calculation and divide by 1,000:

- The number of on-demand units consumed =
`(199,000 / 1,000) = 199`

If the time series on-demand price is $7.5 for up to **one unit of 1,000
time series**, the total monthly cost for this use case = `$7.5 * 199 = $1592.50`

per month.

### Metric Packs Time Series Consumption

Extending the above example, we can see how purchasing individual time series packs will extend your time series entitlement.

- Two Prometheus Servers
- Prometheus Server 1 generates
`50,000`

time series - Prometheus Server 2 generates
`150,000`

time series - One Sysdig agent that collects
`1,000`

time series `100`

pre-purchased time series packs, which is equivalent to`100,000`

time series

The billing for the month is calculated as follows:

- Total subscription capacity: (Total time series consumption - (time series entitlement from time series pack + subscription entitlement))
`(50,000 + 150,000 + 1,000) - (100,000 + 2,000) = 99,000`

*Pre-purchased time series packs also entitle you to 1,000 time series per month
per pack.*

If the pre-purchase price for time series packs is $5 ($2.50 less per 1,000
time series than the on-demand usage price), and you’ve purchased 100 packs,
that brings your pre-purchase time series entitlement cost to **$500** per
month.

To calculate your overall monthly cost, you would determine the total time series entitlement subtracted from the total time series consumed, then include the amount already paid for in pre-paid time series packs. Any resulting time series overage beyond the included entitlement plus the pre-purchased time series pack entitlement would be billed at the on-demand rate of $7.50 for each 1,000 time series block.

Total number of time series consumed =

`(50,000 + 150,000 + 1,000) = 201,000`

Total time series entitlement:

`(100,000 + 2,000) = 102,000`

Time series overage:

`(201,000 - 102,000) = 99,000`

On-demand time series cost:

`(99,000 / 1,000) * 7.50 = $742.50`

(we would be purchasing 99 1,000 packs of on-demand time series as the overage above what is already covered by our entitlement)Total monthly time series cost = Cost of pre-purchased time series packs + cost of total overage:

`($500 + $742.50) =`

**$1,242.50**
