show run command with date

[Carlton Patterson]

Hello Community,

Is there a command in the IOS that will pick up todays date?

For example, show loggin | inc <todays_date>

Cheers

Carlton

you need to use the following command

show loggin | inc Dec  6

where the date use is 1 - 9 use 2 spaces between month and date, 10 - 31 is a single space

Hi Lee,

Thanks for responding. I didn't explain myself. I'm aware that I could do show loggin | inc Dec. However, I was hoping that there might be some kind of variable that would input today's date in show loggin | inc   ?

cheers

Carlton,

There's nothing out of the box as far as I know, but you possibly may be able to script something if that's important to you to be able to do. Generally, logging is sent to a syslog server in which you would be able to search by date. Let me know if the scripting thing is a viable solution for you....

HTH,

John

John, a script would be great mate.

[Carlton Patterson]

Hi John,

Do you think you might be able compile a script today? Just wondering mate.

Well, I have one, but it's not pretty. It's tcl which your router should support. To run it manually on the router, here's what I suggest (although I haven't been able to do much research):

Copy this to your router or a tftp server.

Here's the script:

---- Copy Below -----

set date [ exec {show clock} ]

set day [lindex $date 4]

set mth [lindex $date 3];

if { [ string length $day ] == 2 } {

    set result "${mth} ${day}"

} else {

    set result "${mth}  ${day}"

}

show log | inc $result

---- End of script -----

You can then create an alias on the router that you want to use this script on to launch it:

alias exec todayslogs tclsh tftp:///currentdate.tcl

OR

alias exec todayslogs tclsh flash://currentdate.tcl

***** My Disclaimer: ******

I tested this on my router and it works great, although I can't guarantee that it will work correctly on yours. It's a start though....

HTH,
John

Hi John,

I tried running as follows:

event manager run flash:/logscpcurrentdatev.tcl

but I got the following error message:

Embedded Event Manager policy flash:/logscpcurrentdatev.tcl not registered with event none Event Detector

I have attached the script. I modified it a little

[alesuarez]

a question, how do you save the tcl script in the router? when you dont have access neither a ftp nor a tftp, only have access to the router by telnet. thanks

[Joe Clarke]

You can use tclsh for this:

Router#tclsh

Router(tcl)#set fd [open flash:file.txt w]

Router(tcl)#puts $fd {

<Paste contents here.>

}

Router(tcl)#close $fd

Thanks mate. Going to check it out now...

I look forward to hearing the outcome if you don't mind posting back

Hi John,

As you can see I tried modifying so that I could run it from event manager but it wouldn't work.

Any ideas?

Cheers

You won't be able to run this script from event manager...I tried and came back with a blank prompt because event manager runs in a different tty. TCL does as well, but it outputs to the current tty that it was run from.

*** Edit ***

I wont' say you "can't" run it from event manager, but I didn't play around with it too much.

Try running with "tclsh flash://currentdatev.tcl" and see if it at least works. If it does, I can work with eem to see what I can come up with..

HTH,
John

Hi John,

Thanks again for working with me on this.

When I run it with tclsh flash:/currentdatev.tcl I get a blank screen.
