sla_get

Read-only

Retrieve SLA definitions to inspect availability targets, SLO percentages, schedules, and linked service tags.

Instructions

Retrieve SLA definitions. SLAs measure service availability against defined targets (e.g. 99.9% uptime). Each SLA has a schedule, SLO (Service Level Objective) percentage, and is linked to services via service tags. Use selectServiceTags, selectExcludedDowntimes, and selectSchedule in extra_params to include related objects.

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: description, effective_date, name, period, slaid, slo, status, timezone. Text properties cannot be filtered; use 'search' for them.
outputNoProperties of the sla object to return. Pass 'extend' for all, 'count' for the number of matches only, or a list of property names. Default when omitted: slaid, name, slo, status. Properties: description, effective_date, name, period, slaid, slo, status, timezone.
searchNoReturn results whose string properties contain the given pattern (case-insensitive; '*' is a wildcard when searchWildcardsEnabled is true). Example: {"name": "web"}. Keys: description, name, timezone.
serverNoTarget Zabbix server. Available: default. Defaults to 'default' if omitted.
slaidsNoReturn only SLAs 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: slaid, name, period, slo, effective_date, timezone, status, description (a list for several; pair with 'sortorder'). No other property is sortable.
sortorderNoSort order: 'ASC' (ascending) or 'DESC' (descending).
serviceidsNoReturn only SLAs linked to the given services.
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 sla.get parameters, merged into the request as-is. Parameters: evaltype, service_tags. Sub-object selects (value 'extend', 'count' or a list of property names): selectExcludedDowntimes, selectSchedule, selectServiceTags. 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

B3.3/5.0
Behavior3/5

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

Annotations already declare readOnlyHint=true and openWorldHint=false, so safety is covered. The description adds domain meaning but says nothing about result volume, pagination, or the default property set returned, which for a 14-parameter read tool with no output schema is a meaningful gap; the agent cannot predict response shape from this text alone.

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

Conciseness3/5

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

The text is short, front-loaded with the core verb and resource, and free of filler. It is slightly thin rather than verbose, and the final sentence is a bare pointer to parameters rather than a meaningful statement about behavior, so efficiency is fine but not exemplary.

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

Completeness3/5

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

Given a rich 14-parameter schema that is fully documented, the description's main remaining job is orientation and tool selection, and it performs only the first. It explains what an SLA is but does not tell an agent when to pick sla_get versus sla_getsli or service_get, leaving the most consequential context for this complex surface unaddressed.

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%, with limit, filter, output, sortfield, and extra_params each documented in detail, so the baseline is 3. The description only echoes the extra_params select keys that the schema already explains ('extend', 'count', or a list), adding no new syntax or semantics beyond the structured fields.

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

Purpose4/5

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

The description uses a specific verb and resource ('Retrieve SLA definitions') and adds domain framing (availability targets, schedule, SLO percentage, linkage to services via service tags). It implicitly separates itself from the sibling sla_getsli by focusing on definitions rather than SLA values, but never names that sibling, so the differentiation is left to inference.

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

Usage Guidelines3/5

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

There is a useful in-description pointer ('Use selectServiceTags, selectExcludedDowntimes, and selectSchedule in extra_params to include related objects'), which is real usage guidance for expanding results. However, there is no when-to-use guidance against the obvious alternative sla_getsli, or against service_get for service-level data; the agent must infer which tool answers which question.

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