auditlog_get

Read-only

Retrieve Zabbix audit log entries to review configuration changes and login events for security, compliance, and forensic investigations; filter by time window or user to narrow results.

Instructions

Retrieve audit log entries (read-only). The audit log records every configuration change and login/logout event in Zabbix, including who made the change, when, what object was affected, and the old/new values. Essential for security auditing, compliance, and forensic investigation. Use time_from/time_till to limit the time window and userids to focus on a specific user's activity. Results can be large -- always use limit or time filters. The newest entries come first unless a sort is given, so 'limit' keeps the latest ones.

Input Schema

NameRequiredDescriptionDefault
limitNoMaximum number of results to return.
filterNoReturn 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: action, auditid, clock, ip, recordsetid (6.0+), resource_cuid (7.0+), resourceid, resourcename, resourcetype, userid, username (6.0+). Text properties cannot be filtered; use 'search' for them.
outputNoProperties of the auditlog object to return. Pass 'extend' for all, 'count' for the number of matches only, or a list of property names. Default when omitted: auditid, userid, action, resourcetype, clock. Properties: action, auditid, clock, details (6.0+), ip, recordsetid (6.0+), resource_cuid (7.0+), resourceid, resourcename, resourcetype, userid, username (6.0+).
searchNoReturn results whose string properties contain the given pattern (case-insensitive; '*' is a wildcard when searchWildcardsEnabled is true). Example: {"name": "web"}. Keys: details (6.0+), ip, resourcename, username (6.0+).
serverNoTarget Zabbix server. Available: default. Defaults to 'default' if omitted.
useridsNoReturn only audit log entries for actions performed by these user IDs.
auditidsNoReturn only audit log entries with the given IDs.
raw_jsonNoStrips 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.
sortfieldNoSort by one or more of: auditid, userid, clock (a list for several; pair with 'sortorder'). No other property is sortable. When omitted, the result is sorted by auditid with the newest first.
sortorderNoSort order: 'ASC' (ascending) or 'DESC' (descending). 'DESC' while 'sortfield' is omitted (newest first); 'ASC' alone returns the oldest first.
time_fromNoReturn only audit log entries created 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). Use for scoping queries to a specific time window.
time_tillNoReturn only audit log entries created 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).
countOutputNoReturn the count of matching results instead of the actual data.
searchByAnyNoIf true, return results matching ANY search field (OR). Default is ALL fields (AND).
extra_paramsNoOther native auditlog.get parameters, merged into the request as-is. Sub-object selects (value 'extend', 'count' or a list of property names): . 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.
searchWildcardsEnabledNoIf true, enable * and ? wildcards in search patterns.

  2. First observedv1.41.0

TDQS

A4.4/5.0
Behavior4/5

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

readOnlyHint=true already tells the agent this is a safe read, so the description adds real value beyond the annotation: it discloses that result sets can be large, that the newest entries come first by default, and that limit therefore trims to the most recent rows. It does not discuss permission scoping (whether a user sees all audit records) or pagination beyond limit, which keeps it just short of a 5.

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

Conciseness5/5

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

It is short and front-loaded: purpose first, then what the log contains, then the practical constraint about volume, then the ordering caveat. Every sentence carries information an agent would otherwise have to discover by trial.

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?

For a 16-parameter read tool with no output schema and full schema documentation, the description covers the decisions an agent must make: whether to bound time, whether to filter by user, and how to avoid oversized responses. The remaining gap is that it does not sketch the returned record shape, but the output parameter and 100% schema coverage largely compensate.

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

Parameters4/5

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

Schema coverage is 100%, so the baseline is 3; the description goes further by tying specific parameters to intent (time_from/time_till for scoping, userids for actor focus, limit for volume control) and by explaining the interaction between default ordering and limit. It says nothing about filter, search, output, or raw_json, but those are fully documented in the schema.

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?

The description gives a specific verb (retrieve) plus the resource (audit log entries) and then defines precisely what those entries contain: configuration changes and login/logout events with actor, time, object, and old/new values. That content definition cleanly distinguishes it from every sibling *_get tool, none of which cover audit history.

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

Usage Guidelines4/5

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

It states the operational conditions explicitly: use time_from/time_till to bound the window and userids to focus on one user, and always apply limit or time filters because result sets can be large. There are no exclusions or named alternative tools, but with this resource there is no sibling substitute, so the missing 'instead use X' clause is minor.

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