|---|
| 102 | <P> |
|---|
| 103 | A named and optionally tagged set of records to be sent to the metrics |
|---|
| 104 | system. <p/> |
|---|
| 105 | |
|---|
| 106 | A record name identifies the kind of data to be reported. For example, a |
|---|
| 107 | program reporting statistics relating to the disks on a computer might use |
|---|
| 108 | a record name "diskStats".<p/> |
|---|
| 109 | |
|---|
| 110 | A record has zero or more <i>tags</i>. A tag has a name and a value. To |
|---|
| 111 | continue the example, the "diskStats" record might use a tag named |
|---|
| 112 | "diskName" to identify a particular disk. Sometimes it is useful to have |
|---|
| 113 | more than one tag, so there might also be a "diskType" with value "ide" or |
|---|
| 114 | "scsi" or whatever.<p/> |
|---|
| 115 | |
|---|
| 116 | A record also has zero or more <i>metrics</i>. These are the named |
|---|
| 117 | values that are to be reported to the metrics system. In the "diskStats" |
|---|
| 118 | example, possible metric names would be "diskPercentFull", "diskPercentBusy", |
|---|
| 119 | "kbReadPerSecond", etc.<p/> |
|---|
| 120 | |
|---|
| 121 | The general procedure for using a MetricsRecord is to fill in its tag and |
|---|
| 122 | metric values, and then call <code>update()</code> to pass the record to the |
|---|
| 123 | client library. |
|---|
| 124 | Metric data is not immediately sent to the metrics system |
|---|
| 125 | each time that <code>update()</code> is called. |
|---|
| 126 | An internal table is maintained, identified by the record name. This |
|---|
| 127 | table has columns |
|---|
| 128 | corresponding to the tag and the metric names, and rows |
|---|
| 129 | corresponding to each unique set of tag values. An update |
|---|
| 130 | either modifies an existing row in the table, or adds a new row with a set of |
|---|
| 131 | tag values that are different from all the other rows. Note that if there |
|---|
| 132 | are no tags, then there can be at most one row in the table. <p/> |
|---|
| 133 | |
|---|
| 134 | Once a row is added to the table, its data will be sent to the metrics system |
|---|
| 135 | on every timer period, whether or not it has been updated since the previous |
|---|
| 136 | timer period. If this is inappropriate, for example if metrics were being |
|---|
| 137 | reported by some transient object in an application, the <code>remove()</code> |
|---|
| 138 | method can be used to remove the row and thus stop the data from being |
|---|
| 139 | sent.<p/> |
|---|
| 140 | |
|---|
| 141 | Note that the <code>update()</code> method is atomic. This means that it is |
|---|
| 142 | safe for different threads to be updating the same metric. More precisely, |
|---|
| 143 | it is OK for different threads to call <code>update()</code> on MetricsRecord instances |
|---|
| 144 | with the same set of tag names and tag values. Different threads should |
|---|
| 145 | <b>not</b> use the same MetricsRecord instance at the same time. |
