This document contains general requirements and rules for inserting and using your custom data. Additional requirements may apply based on the method you use.
Access to your custom data depends on your Insights subscription's data retention.
When inserting custom events and attributes to Insights, follow these general requirements for supported data types, naming syntax, and size:
Total maximum size or length: 1 MB maximum per POST. We highly recommend using compression.
The Event API has additional HTTP rate limits.
|Attribute data types||
Attribute values can be either a string or a numeric integer or float.
If your attribute values contain date information, define it as an unformatted Unix timestamp (in seconds or milliseconds) by using the Insights data formatter.
Maximum total attributes per event: 254. Exception: If you use the APM agent API, the max is 64. Maximum total attributes per event type: 48,000.
Attribute names can be a combination of alphanumeric characters, colons (

Do not use words reserved for use by NRQL and Insights.
|Null values||The database does not store any data with a null value.|
Avoid using the following reserved words as names for events and attributes. Otherwise, unexpected results may occur.
This is not a complete list. In general, it's a good practice to avoid using MySQL-reserved words to avoid collision with future New Relic functionality.
This is a reserved attribute name. If it is included, it will be dropped during ingest.
Value must be an integer. If it is not an integer, the attribute name and value will be dropped during ingest.
The event type as stored by New Relic Insights. New Relic agents and scripts normally report this as
Must be a Unix epoch timestamp. You can define timestamps either in seconds or in milliseconds. It must be +/-1 day (24 hours) of the current time on the server.
|NRQL syntax terms||
If you need to use NRQL syntax terms as attribute names, they must be enclosed in backticks; for example,

Event type limits
The current limit for total number of
eventType values is 250 per sub-account in a given 24-hour time period. If a user exceeds this limit, New Relic may filter or drop data. Event types include:
- Default events from New Relic agents
- Custom events from New Relic agents
- Custom events from Insights custom event inserter
