Introduction

BlueMind's Tick package is used to monitor large amounts of data (metrics). Some monitored data is raw, but other data is the result of pre-processing to provide more relevance make interpretation and analysis easier.

Every metric has its own tree structure which can contain:

  • datalocation: server name
  • host: host name or IP 
  • meterType: data type
    • gauge: instant measurement
    • counter: incremental counter
    • distsum: counter-amount data pair 
      e.g.:
      • bm-lmtpd.emailSize = (number of emails, total size of emails)
      • bm-lmtpd.emailRecipients = (number of emails, number of recipients)
    • timer: same as distsum but with the amount always expressed in nanoseconds
  • status: depending on the type of data, this status may be ok/failed (e.g. request successful/failed), success/failure (e.g. authentication successful/failed), etc.

Common data

As a rule, metrics are grouped by component.

JVM

There are JVM metrics for every JVM component:

  • bm-<composant>.hprof: the number of hprof files on the server can be used as an indication of a crash
  • bm-<composant>.jvm.*: all the jvm information for this component (current or maximum memory usage, etc.)

Heartbeat

In each component with interactions with the core, you will find the following metrics which are used to make sure that the component is receiving the core's health data:

Metric NameTypeContentAdditional Information
heartbeat.receiver.ageGaugeage of the last heartbeat received

The time between 2 heartbeats.

The core is supposed to send its health information every 4 seconds. Durations exceeding this, or exceeding 8 seconds, may indicate some issue.

heartbeat.receiver.failuresCounternumber of failed heartbeats
heartbeat.receiver.latencyGaugeheartbeat delivery timeTime between the heartbeat being sent by the core and it being received by the component.
heartbeat.receiver.latencyMaxGaugemaximum heartbeat delivery time
heartbeat.receiver.receivedCounternumber of successful heartbeats

Hazelcast

The servers members of the hazelcast cluster comprise the following metric:

Metric NameTypeContentAdditional Information
cluster.membersGauge
The value of this metric must be '3'

Metrics

Metric NameTypeContentAdditional Information
agent.metricsGatheredCounternumber of metrics collected by the agentThis metric is mostly useful for checking whether the agent is working properly: no data means that the agent isn't collecting anything and therefore that it is no longer working.
agent.vmware*
agent host server data

The agent is enabled only if vmware tools are detected on the BlueMind host servers. In this case, the "vSphere Guest SDK" metrics are extracted and historized.

These metrics are used to diagnose issues with BlueMind's virtualization on vmware.

  • kind: maintenance - maintenance page displays
  • kind: protected - protected pages displays

Used, among other things, to check the number of times the maintenance page has been displayed. Too many "maintenance" requests may indicate an issue.
