history_get

Read-only

Retrieve historical Zabbix item values by item or host ID, with filters for time range and data type. Use it to inspect raw metric history for troubleshooting or analysis.

Instructions

Retrieve historical item data (collected metric values). History stores every collected value and is the most granular data source in Zabbix. Always specify the 'history' parameter to select the correct data type (0=numeric float, 1=character/string, 2=log, 3=numeric unsigned, 4=text, 5=binary on 7.0+, 6=JSON on 8.0+; Zabbix assumes 3 when omitted). Use 'time_from' and 'time_till' (Unix timestamp, ISO 8601 or a relative time such as now-1h) to bound the time range. Combine with 'itemids' or 'hostids' to target specific metrics. For long time ranges, consider using trend.get instead as it returns aggregated min/avg/max values and is more efficient.

Input Schema

TableJSON Schema

Name	Required	Description
`limit`	No	Maximum number of results to return.
`filter`	No	Return only results whose properties exactly match the given values (a single value or a list of values per key). Example: {"status": 0} or {"status": [0, 1]}. Keys: clock, itemid, ns, value. Text properties cannot be filtered; use 'search' for them.
`output`	No	Properties of the history object to return. Pass 'extend' for all, 'count' for the number of matches only, or a comma-separated list of property names. Default when omitted: 'extend'. Properties: clock, itemid, ns, value.
`search`	No	Return results that match the given pattern (case-insensitive by default). Example: {"name": "web"} finds 'Web Server', 'my-web-app', etc.
`server`	No	Target Zabbix server. Available: default. Defaults to 'default' if omitted.
`history`	No	History data type to retrieve: 0=numeric float, 1=character/string, 2=log, 3=numeric unsigned (Zabbix default when omitted), 4=text, 5=binary (7.0+), 6=JSON (8.0+). Must match the item's value_type, otherwise the result is empty.
`hostids`	No	Return only history for the given host IDs.
`itemids`	No	Return only history for the given item IDs.
`raw_json`	No	Strips the security disclaimer preamble from the response so it is pure JSON. Default: false. Requires the bearer token to have 'allow_raw_json' explicitly enabled by an operator in the admin portal - tokens without that policy receive a PolicyError instead. WARNING: setting true bypasses the prompt-injection mitigation marker that wraps untrusted Zabbix data (host names, item descriptions, problem text). LLM clients (Claude, GPT, Cursor, ...) should leave this false; only programmatic non-LLM consumers (Python scripts, n8n workflows that json.loads the result) should set true.
`sortfield`	No	Sort by one or more of: itemid, clock, ns (7.0+) (comma-separated for several; pair with 'sortorder'). No other property is sortable.
`sortorder`	No	Sort order: 'ASC' (ascending) or 'DESC' (descending).
`time_from`	No	Return only data collected after this time (Unix timestamp, ISO 8601 date-time such as 2026-04-01T08:00:00Z, or a relative time such as now-1h, now/d or now-7d/d; a value without a zone is read in the zone resolved for the call) (inclusive).
`time_till`	No	Return only data collected before this time (Unix timestamp, ISO 8601 date-time such as 2026-04-01T08:00:00Z, or a relative time such as now-1h, now/d or now-7d/d; a value without a zone is read in the zone resolved for the call) (inclusive).
`countOutput`	No	Return the count of matching results instead of the actual data.
`searchByAny`	No	If true, return results matching ANY search field (OR). Default is ALL fields (AND).
`extra_params`	No	Other native history.get parameters, merged into the request as-is. Parameters: maxValueSize (8.0+). Any other key is refused here, because Zabbix would silently ignore it. For a parameter you are sure exists on your release but is not listed, use zabbix_raw_api_call.
`searchWildcardsEnabled`	No	If true, enable * and ? wildcards in search patterns.

A4.3/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered. The description adds real behavioral context beyond that: it discloses the silent default (Zabbix assumes type 3 when 'history' is omitted) and the trap that a value_type mismatch yields an empty result rather than an error. It stops short of describing pagination or size-limit behavior, so it is strong but not exhaustive.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

One front-loaded paragraph that leads with purpose, then key parameters, then the alternative, which is the correct order for an agent scanning for a decision. It is dense but every sentence carries a directive, with only minor redundancy against the schema's own history/time documentation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, return-value explanation is unnecessary, and the description covers the operationally important gaps: required data-type matching, time range format, targeting, and the trend_get fallback. For a 17-parameter read tool this is nearly complete, though it does not surface the raw_json policy/injection caveats that live only in the schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100% and an output schema exists, so the schema already documents limit, filter, output, search, history, time bounds, sorting and the rest. The description largely restates what the schema says (the history enum and the time format are duplicated verbatim), so it adds little parameter meaning beyond the structured fields. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb and resource ('Retrieve historical item data (collected metric values)') and immediately situates it as the most granular data source in Zabbix, which cleanly separates it from the aggregated trend_get sibling. An agent can tell what this does and how it differs from related tools without opening the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Gives explicit conditional guidance: always set 'history' to match the data type, bound the range with time_from/time_till, narrow with itemids/hostids, and prefer trend_get for long ranges because it returns aggregated min/avg/max more efficiently. This is a named alternative with the selecting condition, so routing is unambiguous.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
