Setting up a historical server recording

As a rough guide just to see how it all works after you have the monitor server and historical server running execute the following on the historical server (log in using isql);

Example

Suppose you want to record, once every second, the reads, writes, and total I/O per device on an Adaptive Server that is monitored by the SMS1100 Monitor Server. You can use the following steps to record the data, create a table to accept the data, and then use the bcp utility to import the data into the table. In this example, the view data file that is created by Historical Server for the view is d1_1_device_io.

1. Use isql to log in to Historical Server.
2. Record the data by using the following commands:

hs_create_recording_session capella_mon, 30

go

hs_create_view device_io,

    "device name", "value for sample",

    "device reads", "value for sample",

    "device writes", "value for sample",

    "device i/o", "value for sample"

go

hs_initiate_recording

go

1. Use isql to log in to Adaptive Server. Because the recording session contains only one view (“device_io”), create just one table in the pubs2 database to store data for that view by using the following transact sql commands:

use history

go

create table device_io

(

sample_time          datetime         not null,

device_name          varchar (255)    null,

device_reads_val     int              null,

device_writes_val    int              null,

device_io_val        int              null,

)

go

1. After the recording session is complete, you can use bcp to import data from the view’s data file into the database table. Use the following commands:

bcp history..device_io in d1_1_device_io -c 
-e d1_1_device_io.err -U username 
-P password -S server –t\,

Appendix

Table of data items and definitions

Table A-1 describes the data items available for inclusion in recording session views. The table lists data items in alphabetical order and provides the following information about each one:

• A definition
• An Adaptive Server release dependency designation
• A result or key designation

Table A-1: Data items and definitions Data item	Description
Application Execution Class Version: 11.5 and later	Configured execution class, if any, for a given application name. Because of override features, the configured execution class does not necessarily reflect the priority and engine group at runtime. The following notations are used in the monitor: Blank – no execution class is configured for this application. Execution class name – the execution class configured for the application in general, without consideration for specific logins. (That is, an execution class is configured for the application with null scope.) Execution class name followed by asterisk (*) – in addition to the execution class configured for the application in general, additional execution classes are configured for specific logins. (That is, an execution class is configured for the application with null scope and at least one additional execution class is configured for the application with a specific scope.) An asterisk (*) without execution class – no execution class is configured for the application in general, but execution classes are configured for specific logins using this application. (That is, at least one execution class is configured for the application with a specific scope.) Type: Result
Application Name Version: 11.0 and later	Name of application for which other statistics are being accumulated. Views that contain Application Name report only on processes that are active as of the end of the sample period. Application name is mutually exclusive with Process ID in a view. Type: Key
Blocking Process ID Version: 11.0 and later	ID of the process that holds a lock that another process is waiting for, if any. A returned value of zero means that the other process is not blocked. Type: Result
Cache Efficiency Version: 11.0 and later	The number of cache hits per second per megabyte of a particular data cache. Type: Result
Cache Hit Pct Version: 11.0 and later	The fraction of the page reads for objects bound to a particular data cache that are satisfied from the cache computed from the following formula: cache_hits / (cache_hits + cache_misses) * 100 Type: Result
Cache Hits Version: 11.0 and later	The number of times a page read was satisfied from a particular data cache. Type: Result
Cache ID Version: 11.0 and later	The ID of a data cache in Adaptive Server version 11.0 or later. Particular database tables and indexes may be bound to a specific data cache, or all objects in a database may be bound to the same data cache. No object may be bound to more than one data cache. Type: Key
Cache Misses Version: 11.0 and later	Number of times a page read was satisfied from disk rather than from a particular data cache. This data item includes failed attempts to locate pages in the data caches during page allocation. Therefore, the number of physical page reads reported may be overstated. If this occurs, the percentage of data cache misses reported by Cache Hit Pct is understated. Type: Result
Cache Name Version: 11.0 and later	The name of a data cache. Particular database tables and indexes may be bound to a specific data cache, or all objects in a database may be bound to the same data cache. No object may be bound to more than one cache. Type: Key
Cache Prefetch Efficiency Version: 11.0 and later	A percentage comparing the count of pages being reused in large I/O buffers (the denominator) to the number of those pages that were ever referenced by Adaptive Server. When a buffer is reused, all of the pages in it are counted as reused. Buffers are reused when there are no free buffers in the pool to accept a new physical read from a database device. The number of reused pages referenced by Adaptive Server divided by the result of the number of pages per buffer multiplied by the number of reused buffers indicates the effectiveness of large I/O fetches. Regardless of how many buffer pools are configured in a named data cache, Adaptive Server only uses two of them. It uses the 2K buffer pool and the pool configured with the largest-sized buffers. Prefetch effectiveness does not apply to the 2K buffer pool, since 2K grabs are not considered large I/O. Therefore, prefetch effectiveness applies to the largest buffer pool in the cache. For example, if a data cache has pools of buffers sized 2K, 8K, and 16K, the 8K pool is not used, and this metric reflects the effectiveness of large I/O in the 16K buffer pool. If the ratio is large, then prefetching is effective; otherwise, prefetching is not providing much benefit. This may suggest that a buffer pool should be eliminated (or it may imply that a clustered index on some table is fragmented, and that the index should be dropped and re-created). Type: Result
Cache Refer and Reuse Version: 11.0 and later	The number of pages in buffers that were both referenced and reused. This count is employed when determining the efficiency of prefetching buffers (see Cache Prefetch Efficiency). This data item, unlike Cache Prefetch Efficiency, includes activity in the default 2K buffer pool. See Cache Prefetch Efficiency for a definition of buffer reuse. Type: Result
Cache Reuse Version: 11.0 and later	The number of pages in buffers that were reused. A large value indicates a high rate of turnover (of buffers in this memory pool), and suggests that the pool may be too small. A zero value suggests that this memory pool may be too large. This data item, unlike Cache Prefetch Efficiency, includes activity in the default 2K buffer pool. See Cache Prefetch Efficiency for a definition of buffer reuse. Type: Result
Cache Reuse Dirty Version: 11.0 and later	The number of times that a buffer that was reused had changes that needed to be written. A non-zero value indicates that the wash size is too small. See Cache Prefetch Efficiency for a definition of buffer reuse. Type: Result
Cache Size Version: 11.0 and later	The size of a data cache, in megabytes. Type: Result

Connect Time Version: 11.0 and later	Number of seconds elapsed since the process was started or since the session was started, whichever is smaller. Type: Result
CPU Busy Percent Version: 11.0 and later	Percentage of total server CPU ticks that the Adaptive Server CPU was busy. Type: Result
CPU Percent Version: 11.0 and later	If used in a view with Process ID, this is the percentage of time a single process was in the Running state over the time all processes were in the Running state. If used in a view with Application Name, this is the percentage of time the set of processes running a given application were in the Running state over the time all processes were in the Running state. Type: Result
CPU Time Version: 11.0 and later	If used in a view with no keys, this data item is the total CPU busy time, in seconds, on the server. If used with keys, this data item is the busy time, in seconds, that was used by each process, application, or engine. Process ID and Application Name are mutually exclusive. Type: Result
CPU Yields Version: 11.0 or later	Number of times that the Adaptive Server yielded to the operating system. Type: Result
Current Application Name Version: 11.0 and later	The name of the application that is currently executing on a particular process. Type: Result

Otherwise, the statement is the currently executing SQL statement in the stored procedure uniquely identified by these two IDs. Type: Result
Current Stmt Batch Text Enabled Version: 11.5 and later	Reports whether Adaptive Server (version 11.5 and later) is saving the SQL text of the currently executing query batches and, if so, how much.

The currently executing SQL statement is in the query batch if both Current Stmt Procedure Database ID is equal to 0 and Current Stmt Procedure ID is equal 0. Otherwise, the currently executing SQL statement is in the stored procedure uniquely identified by these two IDs. A value of 0 indicates partial result data for the currently executing SQL statement. In other words, this SQL statement began executing before monitoring began. Performance metrics are available but numbers reflect only the time period since the start of monitoring. Type: Result
