Returns a 'Detected Issues' section with CRITICAL/WARNING findings and actionable remediation steps, followed by raw diagnostic data. Use this tool FIRST whenever a user asks why a VM is not starting, stuck in Provisioning, crashlooping, failing to migrate, or exhibiting unexpected behavior. Automatically detects: missing StorageClasses, invalid PVC specs, dangerous cloud-init commands (shutdown/halt), nodeSelector migration blockers, failed migrations, and pod crashloops.

• list_metrics - MANDATORY FIRST STEP: List all available metric names in Prometheus.

YOU MUST CALL THIS TOOL BEFORE ANY OTHER QUERY TOOL

This tool MUST be called first for EVERY observability question to:

1. Discover what metrics actually exist in this environment
2. Find the EXACT metric name to use in queries
3. Avoid querying non-existent metrics
4. The 'name_regex' parameter should always be provided, and be a best guess of what the metric would be named like.
5. Do not use a blanket regex like .* or .+ in the 'name_regex' parameter. Use specific ones like kube., node., etc.

REGEX PATTERN GUIDANCE:

• Prometheus metrics are typically prefixed (e.g., 'prometheus_tsdb_head_series', 'kube_pod_status_phase')
• To match metrics CONTAINING a substring, use wildcards: '.tsdb.' matches 'prometheus_tsdb_head_series'
• Without wildcards, the pattern matches EXACTLY: 'tsdb' only matches a metric literally named 'tsdb' (which rarely exists)
• Common patterns: 'kube_pod.' (pods), '.memory.' (memory-related), 'node_.' (node metrics)
• If you get empty results, try adding '.*' before/after your search term

NEVER skip this step. NEVER guess metric names. Metric names vary between environments.

After calling this tool:

1. Search the returned list for relevant metrics
2. Use the EXACT metric name found in subsequent queries
3. If no relevant metric exists, inform the user

• name_regex (string) (required) - Regex pattern to filter metric names. IMPORTANT: Metric names are typically prefixed (e.g., 'prometheus_tsdb_head_series'). Use wildcards to match substrings: '.tsdb.' matches any metric containing 'tsdb', while 'tsdb' only matches the exact string 'tsdb'. Examples: 'http_.' (starts with http_), '.memory.' (contains memory), 'node_.' (starts with node_). This parameter is required. Don't pass in blanket regex like '.*' or '.+'.

  • end (string) - Optional end of the time range in RFC 3339 format, e.g. "2025-01-02T00:00:00Z". Narrows the time range to improve query performance.
  • start (string) - Optional start of the time range in RFC 3339 format, e.g. "2025-01-01T00:00:00Z". Narrows the time range to improve query performance.
  • tempoName (string) (required) - The name of the Tempo instance to query. Use tempo_list_instances to discover available instance names.
  • tempoNamespace (string) (required) - The Kubernetes namespace where the Tempo instance is deployed. Use tempo_list_instances to discover available namespaces.
  • tenant (string) - The tenant to query. This parameter is required for multi-tenant instances. Use tempo_list_instances to discover available tenants for each instance.
  • traceid (string) (required) - The trace ID to retrieve, e.g. "26dad4a0e2b0dd9a440dd5ff203a24a4".

• tempo_search_traces - Search for distributed traces in Tempo using TraceQL. Use this tool to find traces matching specific criteria such as service name, HTTP status code, duration, or other span or resource attributes.

IMPORTANT — "slow" or "long" trace requests: Do NOT guess a duration threshold. First call this tool WITHOUT a duration filter to establish a latency baseline, then use that baseline to set a sensible threshold. Both steps are required — do NOT skip the second search with the duration filter. Skip this two-step process only when the user provides an explicit duration (e.g. "find traces slower than 2s").

• end (string) - End of the time range in RFC 3339 format, e.g. "2025-01-01T00:00:00Z". Use "NOW" for current time. Both start and end should be provided to search the full time range; if omitted, only a small window of recent data is searched.
• limit (integer) - Maximum number of traces to return. Defaults to the server-side limit if not specified.
• query (string) (required) - A TraceQL query expression. Format: query: "{ <filters joined by &&> }"

Filters:

• service name: resource.service.name="" (string, use quotes)
• HTTP status code: span.http.response.status_code=<code> (number, no quotes)
• duration: duration><value like 100ms, 2s, 5m> (no quotes)
• error status: status=error (keyword, NO quotes — do NOT write status="error")

IMPORTANT: status values (error, ok, unset) are keywords, NOT strings. Write status=error, NEVER status="error".

Operators: =, !=, >, <, >=, <=

Common attributes:

• resource.service.name (service name)
• resource.k8s.namespace.name (Kubernetes namespace)
• resource.k8s.deployment.name (Kubernetes deployment)
• resource.k8s.statefulset.name (Kubernetes statefulset)
• resource.k8s.daemonset.name (Kubernetes daemonset)
• resource.k8s.replicaset.name (Kubernetes replicaset)
• resource.k8s.pod.name (Kubernetes pod)
• resource.k8s.container.name (Kubernetes container)
• resource.k8s.job.name (Kubernetes job)
• resource.k8s.cronjob.name (Kubernetes cronjob)
• resource.k8s.node.name (Kubernetes node)
• resource.k8s.cluster.name (Kubernetes cluster)
• span.http.response.status_code (HTTP response code)
• span.http.request.method (HTTP method like GET, POST)
• span.url.full (request URL)
• name (span name / operation name, e.g. "GET /api/users")
• duration (trace duration, e.g. 100ms, 2s)
• status (trace status: ok, error, unset)

Note: older instrumentation may use legacy HTTP attribute names (e.g. span.http.status_code instead of span.http.response.status_code). If a query returns no results, try tempo_search_tags to check which attributes exist.

IMPORTANT:

• Always wrap filters in curly braces { }.
• Do NOT use SQL, PromQL, or Lucene syntax.
• Do NOT omit the "resource." or "span." prefix from attribute names
• When the user refers to a Kubernetes resource type (deployment, pod, namespace, etc.), use the matching resource.k8s.* attribute, NOT resource.service.name.

Examples:

• { resource.service.name="frontend" }
• { resource.k8s.deployment.name="checkout" && span.http.response.status_code>=500 }
• { status=error && duration>2s }

If unsure which attributes to filter on, use tempo_search_tags to discover available attributes before building a query.

• spss (integer) - Maximum number of matching spans to return per trace.

• start (string) - Start of the time range in RFC 3339 format, e.g. "2025-01-01T00:00:00Z". Use "NOW" for current time. Both start and end should be provided to search the full time range; if omitted, only a small window of recent data is searched.

• tempoName (string) (required) - The name of the Tempo instance to query. Use tempo_list_instances to discover available instance names.

• tempoNamespace (string) (required) - The Kubernetes namespace where the Tempo instance is deployed. Use tempo_list_instances to discover available namespaces.

• tenant (string) - The tenant to query. This parameter is required for multi-tenant instances. Use tempo_list_instances to discover available tenants for each instance.

• tempo_search_tags - List available tag names (attribute keys) in Tempo, grouped by scope. Use this tool to discover which attributes are available for building TraceQL queries with tempo_search_traces. For example, this tool may reveal tag names like "service.name" (in the "resource" scope) or "http.response.status_code" (in the "span" scope). To use these in TraceQL queries, prefix them with their scope, e.g. "resource.service.name" or "span.http.response.status_code".

  • end (string) - Optional end of the time range (in RFC 3339 format, e.g. "2025-01-01T00:00:00Z") to filter which traces are considered when listing tags.
  • limit (integer) - Maximum number of tag names to return per scope.
  • maxStaleValues (integer) - Maximum number of consecutive blocks without new tag names before the search stops early. Higher values are more thorough but slower.
  • query (string) - Optional TraceQL query to filter which traces are considered when listing tags, e.g. '{ resource.service.name="payment-service" }' to only show tags present in traces from the 'payment-service' service.
  • scope (string) - Filter tags to a specific scope. One of: "resource" (service-level attributes like service.name), "span" (individual span attributes like http.response.status_code), "intrinsic" (built-in fields like duration, status, name). If omitted, tags from all scopes are returned.
  • start (string) - Optional start of the time range (in RFC 3339 format, e.g. "2025-01-01T00:00:00Z") to filter which traces are considered when listing tags.

Use this tool to discover what values exist for a given tag, e.g. to find all service names (values of "resource.service.name") or all HTTP methods (values of "span.http.request.method"). This is useful for building accurate TraceQL queries with tempo_search_traces.
