Quite simple question...i think so...filename on flash via variables

[Andreas Wittemann]

Hi,

i´m stumbling over my inabilty to use a variable for writing a filename to the routers flash, idea is to collect some information via EEM/kron, and send them to a central site.

Should be easy, but my problem is, i cannot append the routers hostname to the file on the flash. I have actually NO idea how i should do this, avoiding the use of tcl. And the idea is to have exactly one script i can use on all routers, without modifying it, thats for why i want to just use the variable.

Is there a restriction using variables on filesystem operations?

This one works:

event manager applet SYSREPORT
event none
action 1.000 cli command "enable"
action 1.005 cli command "delete /force flash:sysreport"
action 1.010 cli command "sh ver | t flash:sysreport"
action 1.015 cli command "dir flash: | a flash:sysreport"
action 1.020 cli command "sh pro cpu his | a flash:sysreport"
action 1.030 cli command "sh ip int brief | a flash:sysreport"
action 1.040 cli command "sh int des | a flash:sysreport"
action 1.050 cli command "sh ip ospf neigh | a flash:sysreport"
action 1.060 cli command "sh run | a flash:sysreport"

This one not, would have been nicer because i can dampen it to outputs i need:

event manager applet SYSREPORT
event none
action 1.000 cli command "enable"
action 1.005 cli command "delete /force flash:/sysreport.$_info_routername"
action 1.010 cli command "sh ver | i ^Cisco|_ID|uptime|reason|.bin"
action 1.015 cli command "more $_cli_result | t flash:/sysreport.$_info_routername"
action 1.020 cli command "sh pro cpu his"
action 1.025 cli command "more $_cli_result | a flash:/sysreport.$_info_routername"
action 1.030 cli command "sh ip int brief | e down"
action 1.035 cli command "more $_cli_result | a flash:/sysreport.$_info_routername"
action 1.040 cli command "sh int des | i up"
action 1.045 cli command "more $_cli_result | a flash:/sysreport.$_info_routername"
action 1.050 cli command "sh int des | i down"
action 1.055 cli command "more $_cli_result | a flash:/sysreport.$_info_routername"
action 1.060 cli command "sh ip ospf neigh"
action 1.065 cli command "more $_cli_result | a flash:/sysreport.$_info_routername"
action 1.070 cli command "sh ip route | i _00:"
action 1.075 cli command "more $_cli_result | a flash:/sysreport.$_info_routername"
action 1.080 cli command "sh run"
action 1.085 cli command "more $_cli_result | a flash:/sysreport.$_info_routername"

But OK, this one also not:

event manager applet SYSREPORT
event none
action 1.000 cli command "enable"
action 1.005 cli command "delete /force flash:/sysreport.$_info_routername"
action 1.010 cli command "sh ver | t flash:/sysreport.$_info_routername"
action 1.015 cli command "dir flash: | a flash:/sysreport.$_info_routername"
action 1.020 cli command "sh pro cpu his | a flash:/sysreport.$_info_routername"
action 1.030 cli command "sh ip int brief | a flash:/sysreport.$_info_routername"
action 1.040 cli command "sh int des | a flash:/sysreport.$_info_routername"
action 1.050 cli command "sh ip ospf neigh | a flash:/sysreport.$_info_routername"
action 1.060 cli command "sh run | a flash:/sysreport.$_info_routername"

I tried around with this also:

 event manager environment _info_routername $(hostname)

No effect, it´s "$(hostname)" then, as already expected.

How can i manipulate (without tcl) the filename to use variables which should exist already in EEM?

I assumed i can use the variable here:

https://supportforums.cisco.com/document/102581/eem-built-action-variables

But it seems i need to somehow use "action info type routername" to get it, because it throws me the message:

%HA_EM-3-FMPD_UNKNOWN_ENV: fh_parse_var: could not find environment variable: _info_routername

when debugging EEM.

Any help appreciated, i hope it´s just a small thing i didn´t get properly.

All i want is a file called sysreport.<ROUTERNAME> in the flash...should be not too complicated, i thought...

Thank you in advance,

Andreas

Before you can use $_info_routername, you need to call the "info type routername" action.  For example:

action 0.5 info type routername

Your second applet will not work as you can't "more" a variable.  But your last applet should work once you add the action above.

Many thanks Joe, you are the best!

Finished the Script now, works like a charm...every 72 hours a Sysreport-file is generated and uploaded on the FTP-server as desired, including a sortable timestamp...at least until 31.12.2019 ;)

My script now looks like this, maybe it helps others as well, to be :

ip ftp username <FTP-USERNAME>
ip ftp password <FTP-PASSWORD>
