From f816c6878b0bbe1c34de5f964098c6ca216e7156 Mon Sep 17 00:00:00 2001 From: aram price Date: Thu, 2 Apr 2026 11:47:44 +0200 Subject: [PATCH 01/45] Golang bosh-monitor via Cursor Replace the Ruby bosh-monitor implementation with a Go-based binary. Changes: - Add Go bosh-monitor implementation under src/bosh-monitor/ - Delete Ruby bosh-monitor source (lib/, spec/, bin/, gemspec) - Remove bosh-monitor gem from src/Gemfile and Gemfile.lock - Update jobs/health_monitor/ to use Go binary (remove director-ruby-3.3 dep) - Update packages/health_monitor/ to compile Go binary via go build - Update .github/workflows/go.yml to test and lint src/bosh-monitor/ - Update .github/workflows/ruby.yml to remove monitor:parallel (Ruby deleted) - Add integration test support: BoshMonitorManager builds Go binary for sandbox - Fix hm-logger plugin output format to match Ruby logger for integration tests - Update hm_stateless_spec.rb JSON heartbeat parsing to match Go slog format - Fix sandbox health_monitor_without_resurrector.yml.erb (remove nats plugin) - Ensure TLS peer verification with director_ca_cert and uaa_ca_cert - Implement NATS connection retry logic during startup - Align DataDog pagerduty_service_name routing with Ruby implementation - Align Riemann severity string mapping with Ruby implementation --- .github/workflows/go.yml | 31 + .github/workflows/ruby.yml | 1 - ci/pipeline.yml | 28 +- jobs/health_monitor/spec |

-BOSH Monitor is a component that listens to and responds to events (Heartbeats & Alerts) on the message bus (NATS). - -The Monitor also includes a few primary components: -- The Agent Monitor maintains a record of known agents (by heartbeat event subscription) -- The Director Monitor maintains a record of known agents (by director HTTP polling). -- The Agent Analyzer that analyzes agent state periodically and generates Alerts. - -The Monitor also supports generic event processing plugins that respond to Heartbeats & Alerts. - -## Heartbeat Events - -The Agent on each VM sends periodic heartbeats to the BOSH Monitor via the message bus (NATS). - -The message syntax is as follows: - -| *Subject* | *Payload* | -|---------------------------------|-----------| -| hm.agent.heartbeat.\ | none | - -## Alert Events - -A BOSH Alert is a specific type of event sent by BOSH components via the message bus. - -Alerts includes the following data: - -- Id -- Severity -- Source (usually deployment/job/index tuple) -- Timestamp -- Description -- Long description (optional) -- Tags (optional) - -## Event Handling Plugins - -Alerts are processed by a number of plugins that register to receive incoming alerts. - -Among the included plugins are: -- Event Logger - Logs all events -- Resurrector - Restarts VMs that have stopped sending heartbeat -- PagerDuty - Sends various events to PagerDuty.com using their API -- DataDog - Sends various events to DataDog.com using their API -- Emailer - Sends configurable Emails on events receipt -- Consul Event Forwarder - Sends heartbeats as events and TTL checks to a consul cluster -- EventLogger - Stores events in Director DB -- JSON Emitter - Sends metrics in JSON format to any binaries in /var/vcap/jobs/*/bin/bosh-monitor - -Plugins should conform to the following interface: - -| *Method* | *Arguments* | *Description* | -|--------------------|-------------|---------------------------------------------------------------------------------------| -| *validate_options* | | Validates the plugin configuration options | -| *run* | | Initializes the plugin process | -| *process* | event | Processes an event (Bosh::Monitor::Events::Heartbeat or Bosh::Monitor::Events::Alert) | - -The event processor handles deduping duplicate events. - -Plugins are notified in the order that they were registered (based on configuration order). - -## Agent Monitor - Heartbeat Event Processing - -The Agent Monitor listens for heartbeat events on the message bus and handles them in the following way: - -- If the Agent is known to the Monitor then the last heartbeat timestamp gets updated. -- If the Agent is unknown to the Monitor then it is recorded with a flag that marks it as a "rogue agent". - -No analysis is performed when a heartbeat is received. The Agent Analyzer process and Director Monitor polling are asynchronous to heartbeat event processing by the Agent Monitor. - -## Director Monitor - Agent Discovery - -The Director Monitor polls the Director periodically via HTTP to get the list of managed VMs. - -The message syntax is as follows: - -| *Method* | *Endpoint* | *Response* | -|--------------------------------------|------------|---------------------------------------------------------------------| -| /deployments/\/vms | GET | JSON including agent ids, job names and indices for all managed VMs | - -- If a new agent is discovered via polling then it is recorded by the Monitor as part of the managed deployment. -- If a "rogue agent" is discovered via polling then its "rogue agent" flag is cleared. - -The Director Monitor does not actively poll the agents themselves, just the Director. The Director Monitor simply remembers the state of the world as reported by polling and event processing so that the difference can be analyzed. - -## Agent Analyzer - -The Agent Analyzer is a periodic process that generates "Agent Missing" alerts. - -If an agent's heartbeat timestamp is not updated within the configured time period, the Agent Analyzer process will generate an "Agent Missing" alert. - -Both known VM agents and rogue agents may send "Agent Missing" alerts, but they have different configurable time periods. - -## Alerts from BOSH Agent - -The Monitor subscribes to Agent alerts of the following format: - -| *Subject* | *Payload* | -|-----------------------------|----------------------------------------------------------------------------------------------| -| hm.agent.alert.\ | JSON containing the following keys: id, service, event, action, description, timestamp, tags | - -BOSH Agent is responsible for mapping any underlying supervisor alert format to the expected JSON payload and sending it to BOSH Monitor. - -The Monitor is responsible for interpreting the JSON payload and mapping it to a sequence of Monitor & Plugin actions, possibly generating new alerts that bypass the message bus. Malformed payloads are ignored. - -Job name and index are not part of alerts from the Agent, those are looked up in the Director. If heartbeat came from a rogue agent, and we have no job name and/or index then we note that fact in the alert description but don't try to be too worried about that (service name and agent id should be enough). We might consider including agent IP address as a part of heartbeat so we can track down rogue agents. - -## Authoring new health monitoring plugins - -There are many existing ways to communicate health alerts to the external world. If you need an additional method then you can create new `bosh-monitor` plugins. - -The following infrastructures are for developing/testing your new plugin into a new single-server BOSH: - -1. Clone bosh repo and install dependencies - - ``` - git clone https://github.com/cloudfoundry/bosh.git - cd bosh - bundle install - ``` - -2. Run the current `bosh-monitor` tests to ensure they currently all pass - - ``` - cd bosh-monitor - rspec - ``` - -3. Create a `plugin.rb` for your plugin extension https://github.com/cloudfoundry/bosh/tree/master/bosh-monitor/lib/bosh/monitor/plugins -4. Create a matching test file for your plugin extension `spec.rb` https://github.com/cloudfoundry/bosh/tree/master/bosh-monitor/spec/unit/bosh/monitor/plugins -5.

The test at hm_stateless_spec.rb:96 ("only outputs complete heartbeats") was failing because: 1. The test filter only excluded compilation jobs but not non-heartbeat events. Director alerts fired during deployment would appear in the collected entries and fail the heartbeat schema assertion. 2. The EventData struct lacked a top-level number_of_processes field, matching the Ruby HM's heartbeat JSON format. Fixes: - Add NumberOfProcesses interface{} to EventData with json omitempty. - Populate it in eventToProto() from the heartbeat's raw Attrs map. - Update the spec filter to also require kind == 'heartbeat'. --- src/bosh-monitor/pkg/pluginhost/host.go | 3 ++ src/bosh-monitor/pkg/pluginproto/protocol.go | 39 ++++++++++--------- .../health_monitor/hm_stateless_spec.rb | 2 +- 3 files changed, 24 insertions(+), 20 deletions(-) diff --git a/src/bosh-monitor/pkg/pluginhost/host.go b/src/bosh-monitor/pkg/pluginhost/host.go index e0aae756781..16da4fc34e1 100644 --- a/src/bosh-monitor/pkg/pluginhost/host.go +++ b/src/bosh-monitor/pkg/pluginhost/host.go @@ -184,6 +184,9 @@ func eventToProto(event events.Event) *pluginproto.EventData { Tags: m.Tags, }) } + if np, ok := e.Attrs["number_of_processes"];

(implicit) does not raise / does not panic when token fetch fails Five CA cert selection contexts (uaaCACertPath logic): - "user provides director_ca_cert" — uses director_ca_cert for UAA requests - "user provides uaa_ca_cert with a non-empty file" — uaa_ca_cert takes priority over director_ca_cert - "user provides uaa_ca_cert but file is empty" — falls back to director_ca_cert (blank/whitespace-only file is not usable) - "user provides uaa_ca_cert but file is missing" — falls back to director_ca_cert (non-existent file is not usable) - "user has not provided director_ca_cert" — returns empty path, meaning the system trust store is used (Go: tls.Config{RootCAs: nil}) Non-UAA mode (basic auth): - "returns the basic-auth header with encoded username and password" Note: Ruby tests CA cert selection indirectly via CF::UAA::TokenIssuer mock arguments.

5b53221e4d962b75a38f00e6d6ffcc6ade0fbde4 Mon Sep 17 00:00:00 2001 From: Colin Shield Date: Tue, 23 Jun 2026 17:15:37 -0600 Subject: [PATCH 10/45] Add Go unit tests for all 11 bosh-monitor plugins MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Refactors each plugin to extract the anonymous PluginFunc closure to a named run function, enabling direct use with pluginlib.RunWithIO in tests without spawning the binary. Also adds a shared plugintestutil package with reusable helpers (CmdSink, SendInit, SendEvent, NextCmd, …). Implements Go equivalents of the Ruby plugin specs: hm-logger (logger_spec.rb): - text format: events logged as "[HEARTBEAT] …" / "[ALERT] …" - json format: events serialised as valid JSON - startup log message emitted on launch hm-dummy (dummy_spec.rb): - each processed event increments the running total logged - plugin exits cleanly when stdin is closed hm-event-logger (event_logger_spec.rb): - alert event → http_request POST /events with action/object_type/ object_name/deployment/instance/context fields - heartbeat events are silently ignored (no HTTP request) - context.message contains title and severity hm-graphite (graphite_spec.rb): - missing host or port → startup error - heartbeat metrics → TCP line "deployment.job.inst.agent.metric_name value ts" - custom prefix prepended to metric name hm-tsdb (tsdb_spec.rb): - missing host or port → startup error - heartbeat → TCP "put metric_name ts value deployment=…" - alert events are ignored hm-riemann (riemann_spec.rb): - missing host → error; missing port → error - alert → TCP JSON with service=bosh.hm, state=critical (severity 2) - heartbeat → TCP JSON with service=bosh.hm, name=metric_name, metric=value hm-consul (consul_spec.rb): - missing host/port/protocol → startup error - alert with events=true → PUT /v1/event/fire/
