The WI_HOSTMETRICSDAILY table gets its information from WI_HOSTMETRICS hourly data table.
Each record is collected into a daily summary and inserted into the wi_hostmetricsdaily table.
This table also gets its information from the LSB_EVENTS raw table. Each record is filtered for each host and its data summarized according to the memory usage of each job ("memory of jobs by host"), cpu usage ("ut of jobs by host"), and swap usage ("swap of jobs by host"). These three metrics are inserted into WI_HOSTMETRICSDAILY as additional metrics.
The following table describes each column and its source:
Column Name |
Description |
Key |
CLUSTER_CODE |
This is the cluster code. The source is the ClusterName field in the data file. The cluster code is obtained by looking up the ClusterName in the wi_clustercode table and generating a new code if it doesn't exist. |
Primary key |
TIME_STAMP |
This is the time stamp of the record collection, in GMT. The record is collected every localized day. After the record collection, the time stamp is transformed back to GMT and stored in this field. Thus, this time_stamp is always in the GMT form of the localized time at midnight. |
Primary key |
HOST_CODE |
This is the host code. The source is the HostName field in the data file. The host code is obtained by looking up the HostName in the wi_hostcode table and generating a new code if it doesn't exist. |
Primary key |
METRIC_CODE |
This is the metric code. The source is the MetricName field in the data file. The metric code is obtained by looking up the MetricName in the wi_metriccode table and generating a new code if it doesn't exist. |
Primary key |
CORE_HOUR |
This is the core hour, which is based on the localized time_stamp. If the time_stamp is within resulted from a mapping of the original time_stamp in local time. If the time_stamp is within the range of 9am to 5pm on Monday to Friday, this field returns 1, otherwise, it returns 0. A value of 1 means that the data in this record is aggregated from the core_hour portion of the day (9am to 5pm, Monday to Friday). |
Primary key |
MIN_VALUE |
This is the minimum of all the values for this metric in this day. |
|
MAX_VALUE |
This is the maximum of all the values for this metric in this day. |
|
SAMPLING_COUNTER |
This is the number of sampled records being collected into this record. |
|
SUM_VALUE |
This is the sum of all the values for this metric in this day. |
|
INSERT_SEQ |
This is a unique sequence number generated by the system for each new record inserted. |
