However this is a slight coding issues when trying to install the setup.sql in SQL Server 2008 r2:-

This is due to a line in the code:-

Which needs to be changed to the following:-

An Error has occured during report processing. (rsProcessingAborted). Cannot read the next data row for the dataset SESSION_CPU_WAIT_INFO (rsErrorReadingNextDataRow)

The datediff function resulted in an overflow. The number of dateparts separating two date/time instances is too large. Try to use datediff with a less precise datepart.

Again this is a simple fix. Either amend the following code in setup.sql or look for the SP [MS_PerfDashboard].[usp_Main_GetSessionInfo] in the msdb database.

The line to change is:-

sum(convert(bigint, datediff(ms, login_time, getdate()))) – sum(convert(bigint, s.total_elapsed_time)) as idle_connection_time,

to

sum(convert(bigint, CAST( DATEDIFF(minute, login_time, getdate()) as bigint)*60000
+DATEDIFF(millisecond, DATEADD(minute, DATEDIFF(minute, login_time, getdate()), login_time), getdate() )))
-SUM(CONVERT(bigint, s.total_elapsed_time)) as idle_connection_time,

An Error has occured during report processing (rsProcessingAborted). Cannot read the next data row for the dataset CPU_UTILIZATION_HISTORY. (rsErrorReadingNextDataRow).

Arithmetic overflow error converting expression to data type int.

Again this is another simple fix. Either amend the following code in setup.sql or look for the SP [MS_PerfDashboard].[usp_Main_GetCPUHistory] in the msdb database.

The line to change is:-

dateadd(ms, -1 * (@ts_now – [timestamp]), GetDate()) as EventTime,

to

dateadd(ms, -1 * (@ts_now – [timestamp])/1000, GetDate()) as EventTime,

PuTTY enables Windows users to access *nix machines through SSH. For many in the tech industry this tool is absolutely crucial. While it is fairly full featured, it is quite cumbersome for generic SSH use. One may say “Jon, all you need to do is run PuTTY, enter the host name you wish to connect to and provide a user name and password.” This process is certainly fine for a single SSH operation. This becomes quite a pain with multiple hosts at once.

What if there was a way to create a hyperlink which launches PuTTY? One would be able to launch PuTTY from email clients, browsers, spreadsheets, etc… An example link would be: ssh://google.com

What do we need to do?

1. Register a new protocol (in our case, let’s call it “ssh”) to Windows’s registry.
2. Create a batch file that can take in strings such as “ssh://google.com” and massage them and pass them on to putty.exe
3. Point the registry modification to that batch file.

One method of editing the registry is to create a .reg file, save it, right click it and select merge. The .reg file will then be merged with the registry. We will use this method. The key created can always be deleted by later from regedit.

Here is an example .reg file which points the protocol “ssh” to a batch file located at “C:/putty_util.bat” :

REGEDIT4
[HKEY_CLASSES_ROOT\ssh]
@="URL:ssh Protocol"
"URL Protocol"=""
[HKEY_CLASSES_ROOT\ssh\shell]
[HKEY_CLASSES_ROOT\ssh\shell\open]
[HKEY_CLASSES_ROOT\ssh\shell\open\command]
@="\"C:\\putty_util.bat\" %1"

Now save ssh.reg locally, right click it, and select merge.

Note: You can create any new protocol by changing each “ssh” in this .reg file to whatever abbreviation you wish to use for your protocol. You will likewise want to change the string @=”\”C:\\putty_util.bat\” %1″ to point at whatever application you wish to use. In this case, we are using the application C:\putty_util.bat and passing in the first argument we receive to it. In the example of ssh://google.com, we will be passing in the string “ssh://google.com”

Unfortunately, PuTTY does not understand arguments which start off with “ssh://” . As a result, we must use a batch file (C:\putty_util.bat) to remove the “ssh://” and any other oddities. Here is the batch file for my box:

@echo off
set var=%1
set extract=%var:~6,-1%
"C:\Program Files\PuTTY\putty.exe" %extract%

set extract=%var:~6,-1% is telling us to remove the first 6 characters and the last character from var and place that value in extract. The removal of the first 6 characters is the removal of “ssh://”. We remove the last character as there seems to be a trailing slash present in the input to our batch file.

With extract holding just the hostname, we now execute putty.exe and pass in extract as an argument. In this case, putty.exe is located at C:\Program Files\PuTTY\putty.exe. Please change this to the location of your putty.exe. Save this batch file to C:\putty_util.bat

Once this is done, anytime you have a link such as ssh://google.com you should be able to simply click it and launch PuTTY.

I will have a followup post with instructions on how to accomplish the same with ssh in other operating systems.

I’ve used all sorts of tools to duplicate data.

Database replication, Array-based replication, rsync + tar piped to tar over SSH.
On the Windows side: good old teracopy and robocopy.

When rsync and tar where the right tool, I often asked myself why there wasn’t a generic file system replication tool when I completed my work. Well, it appears there is. The cpdup utility provides an easy to use interface to copy a file system from one system to another. In it’s most basic form you can call cpdup with a source and destination file system:

$ cpdup -C -vv -d -I /data 192.168.0.1:/data

root@192.168.0.1's password:
Handshaked with ftp
/data
Scanning /data ...
Scanning /data/conf ...
/data/conf/main.cf.conf          copy-ok
/data/conf/smb.conf              copy-ok
/data/conf/named.conf            copy-ok
Scanning /data/www ...
Scanning /data/www/content ...
Scanning /data/www/cgi-bin ...
Scanning /data/dns ...
/data/lost+found
Scanning /data/lost+found ...
cpdup completed successfully
1955847 bytes source, 1955847 src bytes read, 0 tgt bytes read
1955847 bytes written (1.0X speedup)
3 source items, 8 items copied, 0 items linked, 0 things deleted
3.8 seconds  1007 Kbytes/sec synced   503 Kbytes/sec scanned

This will cause the entire contents of /data to be migrated through SSH to /data on the remote server. It appears cpdup picks up everything including devices and special files, so this would be a great utility to clone systems. There are also options to replace files that are on the remote end, remove files that are no longer on the source, and various others that can be used to customize the copy operation. Nifty utility, and definitely one I’ll be adding to my utility belt.

I enabled query logging by adding the following two statements to the [mysqld] block in the /etc/my.cnf configuration file:

general_log=1
general_log_file=/var/log/query.log

The first line enables logging, and the second line tells MySQL were to write the logs. Once enabled you can see the queries executed against your server by paging out the contents of /var/log/query.log. This will have one or more entries similar to the following:

233 Query     Select FOUND_ROWS()
120212 13:15:07   233 Quit
120212 13:15:12   234 Connect   rsyslog@localhost on
                  234 Init DB   syslog
                  234 Query     SHOW TABLES LIKE '%SystemEvents%'
                  234 Query     SELECT SQL_CALC_FOUND_ROWS id, devicereportedtime, facility, priority, fromhost, syslogtag, processid, infounitid, message FROM SystemEvents ORDER BY id DESC LIMIT 100

Pretty cool, and definitely super useful for debugging problems and figuring out how restrictive you can be with your GRANT statements.
