OpenSearch Support

24/7 OpenSearch Support with a 15-Minute Emergency SLA

AceMQ supports self-managed OpenSearch and Amazon OpenSearch Service in production — unassigned shards after a blue/green deploy, ISM policies that silently stopped rolling over, fine-grained access control errors nobody can decode, and clients still speaking Elasticsearch 7.10. Every ticket reaches a named senior engineer who knows your cluster.

Escalation Path

Your first hour of a OpenSearch outage

Most vendors publish an SLA number. This is what actually happens, minute by minute, when you page a senior AceMQ engineer.

T+0

You page us

Phone, email, or Slack — any channel reaches the on-call senior engineer directly. No web form, no tier-1 queue.

T+15

Named engineer live

A senior engineer who already knows your environment joins a live bridge. Zero cold-start, no re-explaining your topology.

T+30

Root cause isolated

Direct broker access, log and metric review, and a working hypothesis with a rollback plan before we touch anything.

Post

Written RCA

Documented root cause, the fix applied, and the prevention steps — delivered after every P1, not just when asked.

Response Times

SLA tiers, contractually guaranteed

Every tier reaches a senior OpenSearch engineer. There is no tier-1 triage layer to get through.

P1 — Emergency
15 min

Production down, messages not flowing, cluster or broker failure

P2 — Critical
1 hour

Severe degradation, rising error rates, approaching capacity limits

P3 — High
4 hours

Performance issues, configuration problems, non-critical failures

P4 — Standard
Next day

Questions, guidance, best practices, non-urgent improvements

Incident Triage

OpenSearch problems we fix every week

These are real symptoms from real OpenSearch production environments — and the first thing our engineers check when one comes in.

Cluster red or yellow with shards refusing to allocate
What we check firstThe allocation explain API for one unassigned shard. Disk watermarks putting a node into read-only, an allocation awareness attribute no remaining node satisfies, or a shard limit per node are the three answers that cover most cases.
Typical resolutionUnder 1 hour
Elasticsearch clients throw a version error against OpenSearch
What we check firstWhether compatibility.override_main_response_version is enabled. OpenSearch reports its own version at the root endpoint, and older Elasticsearch clients refuse to talk to anything that is not 7.x — this flag is the bridge while you migrate the client libraries properly.
Typical resolutionUnder 1 hour
Heap above 85% and circuit breakers tripping under dashboard load
What we check firstThe parent and fielddata breaker counters against the queries Dashboards is actually firing. A visualisation aggregating on a high-cardinality keyword will pull a large fielddata structure into heap every refresh.
Typical resolution1–2 hours
ISM policy stopped rolling over — one index growing without bound
What we check firstThe ISM explain endpoint for that index. The policy is usually stuck retrying a step because the rollover alias is missing, the index was created outside the matching template, or the policy was edited without bumping the managed index version.
Typical resolutionUnder 2 hours
Amazon OpenSearch Service stuck in a blue/green deployment
What we check firstWhich configuration change triggered it. Instance type, EBS, node count, and several advanced settings each force a full blue/green migration on the managed service — during which write throughput drops and the cluster cannot take another change until it completes.
Typical resolutionSame day
403 security_exception on requests that used to work
What we check firstFine-grained access control mappings against the IAM role actually presented. On the managed service the failure is usually a role that was mapped to an IAM ARN which changed, or a request signed by a different role than the backend role mapping expects.
Typical resolution1–2 hours
Writes rejected once the domain nears its storage limit
What we check firstPer-node EBS usage against the instance type's storage ceiling, plus shard skew across nodes. Managed domains cap volume size by instance family, so an oversized shard on one hot node can hit the wall while the cluster average looks fine.
Typical resolution2–4 hours
Migrated from Elasticsearch and Dashboards features are missing
What we check firstWhich Kibana plugins the old deployment depended on. OpenSearch Dashboards reimplemented alerting, anomaly detection, and reporting rather than inheriting them, so saved objects usually import cleanly while plugin-backed features need rebuilding.
Typical resolutionSame day

Resolution times reflect typical OpenSearch engagements under an active AceMQ support contract. Every P1 closes with a written root-cause analysis.

What's Included

Everything in your OpenSearch support contract

No add-on pricing for incidents. No per-ticket charges. One contract covers the whole surface.

Emergency Incident Response

Red cluster, ingest stalled, or Dashboards down for the team that depends on it. A senior engineer joins a live bridge within 15 minutes with access to diagnose — not an automated ticket acknowledgement.

Root Cause Analysis

Every P1 closes with a written RCA: what failed, why, the fix applied, and the shard, mapping, or policy change that prevents a repeat. Delivered as standard, not on request.

Query & Indexing Performance

Shard sizing, refresh interval and translog durability, mapping design, and query rewrites tuned against your actual traffic mix. We will tell you when the answer is an index template rather than a bigger instance type.

Elasticsearch to OpenSearch Migration

Snapshot-based migration, client library assessment, the compatibility.override_main_response_version bridge, ILM to ISM policy translation, and rebuilding the Kibana features that OpenSearch Dashboards implements differently.

Amazon OpenSearch Service Operations

Managed domain sizing, blue/green deploy planning, fine-grained access control and IAM role mapping, UltraWarm and cold tiering, and the storage ceilings that come with each instance family.

Security, CVE & Version Advisory

Alerts for CVEs affecting your exact OpenSearch version, plus tested upgrade paths across major versions and the security plugin configuration that comes with them.

Anywhere You Run It

We support OpenSearch wherever it's deployed

Cloud, Kubernetes, bare metal, hybrid, and air-gapped — including environments where you can't give us outbound network access.

Why AceMQ

What you get that you don't get elsewhere

Named Engineers, Zero Cold Start

The same senior engineers stay on your account. They know your index templates, your ISM policies, and your ingest pattern — so a P1 call opens with diagnosis instead of you re-explaining the environment.

No Tier-1 Triage Layer

You reach a senior OpenSearch engineer directly by phone, email, or Slack. Nobody collects details to pass along, and no escalation approval stands between you and the person who can fix it.

We Cover What AWS Support Won't

AWS will confirm the domain is healthy and the hardware is fine. They will not debug your mapping, rewrite the aggregation that trips your circuit breaker, or redesign your shard strategy. That gap is exactly where we work.

Both Sides of the Fork

We support OpenSearch and Elasticsearch in production, so migration advice comes from operating both rather than from a preference. Sometimes the honest answer is that the fork you are on is fine and the problem is elsewhere.

Genuine Follow-the-Sun Coverage

Engineers across 26+ countries and every time zone. Your 3am cluster red is someone's mid-afternoon — no overnight skeleton crew, no waiting for a region to come online.

Proactive, Not Just Reactive

Quarterly cluster health reviews plus shared intelligence across our support base. When a version-specific bug surfaces on one customer's cluster, every affected customer hears about it first.
