The script above took a few metrics out of the nginx_status stub page that you can include into your nginx config.

you can do this by including

location /nginx_status {
stub_status on;
access_log off;
}

under your server binding. you might (should) want to restrict access to this to only your internal subnets or localhost.

Once this has been created somewhere (I like /bin for this), you then need to link it into snmp.

you can do this with something along the lines of  the following in your /etc/snmp/snmpd.conf

extend .1.3.6.1.4.1.3031.67 "exim-stats"        /usr/bin/perl   /bin/nginx_stats.pl

output will look something like

First things first, you'll need to get a copy of chan-sccp-b (http://chan-sccp-b.sourceforge.net/) and compile it. If you don't know how to do that, follow the steps on the chan-sccp-b site.

Grab a copy of my freepbx module -

http://wp.daveheavyindustries.com/?attachment_id=357  

http://wp.daveheavyindustries.com/?attachment_id=372

http://wp.daveheavyindustries.com/?attachment_id=378

http://wp.daveheavyindustries.com/?attachment_id=382

I used this sccp.conf, pay attention to the bold lines, this is what tells chan-sccp-b to talk to the mysql database for it's config (which the freepbx module updates).

append this to your res_config_mysql.conf (your username, password  and database name added obviously)

[asterisk]
 dbhost = 127.0.0.1
 dbname = asterisk
 dbuser = username
 dbpass = password

execute mysql-v5.sql from chan-sccp_trunk/conf of your downloaded chan-sccp-b source on your mysql database

mysql --user=user --password=password asterisk < mysql-v5.sql

install the module to freepbx (http://yourpbxip/admin )

Admin -> Module Admin ->Upload Module ->Chose File -> browse to sccp_module.tar.gz (downloaded from above) -> Upload
Admin -> Module Admin -> SCCP Manager -> Install -> Process (bottom right hand corner)  -> Confirm

Two new menus will be added under "Basic"

SCCP Device Manager
SCCP Line Manager
SCCP Button Manager <-- SCCP Button manager cannot be accessed directly, this is called via the SCCP Device Manager

Self explanatory really.

now the last step is to add sccp to the extension list so you can map extensions to SCCP.

edit /var/www/html/admin/modules/core/functions.inc.php around line 6041.

Add this above "$currentcomponent->setoptlistopts('devicelist', 'sort', false);" :-

$currentcomponent->addoptlistitem('devicelist', 'sccp', _("SCCP MAP"));

Now, for elastix, to get the module visible from the elastix gui, I ahd to add two lines to modules/pbxadmin/themes/default/main.tpl, just below extensions

<li><a href="/?menu=pbxconfig&amp;type=setup&amp;display=sccpline" >SCCP Line</a></li>
<li><a href="/?menu=pbxconfig&amp;type=setup&amp;display=sccpdevice" >SCCP Device</a></li>

Install JSON module for PHP

yum info php-pecl-json-1.2.1-4.el5.x86_64

and add to php.ini under Dynamic Extensions

extension=json.so

and you're done!

Usually it'll be something along the lines of  DEV  -> UAT -> PRE_PRODUCTION -> PRODUCTION

So, how do you get updates that have been developed against in DEV to UAT, or from UAT to PREPROD, or PREPROD into production?

well, I wrote a script.. two really, but we'll get to that.

update approval copier.

This copies all update approvals from a source target into a destination target where it has been approved, installed, and where it hasn't failed (on any computer) on the source computer target.

Approve already installed updates

Now... the second is very simpler, it's for when you first deploy WSUS, and you want to copy a baseline for approvals from already updated servers within that target. Note the source and the target are the same (although you could change if it you wanted to copy installed updates as approvals to another target)

Function js_escape(ByRef input_string)

    If NOT IsNull(input_string) AND input_string <> "" Then
        Dim working_string
        working_string = input_string
        working_string = Replace(working_string, vbNewLine, "\n")
        working_string = Replace(working_string, vbTab, "\t")
        working_string = Replace(working_string, "'", "\'")
        ' .. other escape values/strings you may wish to add
        js_escape = working_string
    End If
End Function

The UPS has a metric for each Phase, so for a total output, we have to aggregate the figure. I chose to use Watts in my graphs. The other thing to note is that it requires version 1 of SNMP.

Config below....

$Path is the working directory, needs to exist. $Name is the mrtg name of the instance. $Community is the snmp community (usually public), $host is the hostname/ip of the device. $Title is the friendly name of the instance. Easy as that.

Well, the SNMP oid for this device is enterprises.318.1.1.12.2.3.1.1.2.1 .The current is returned as AMPSx10 .

I.E... will return 100 for 10 amps. The reason for this is that all things snmp expect whole numbers (bits, bytes etc..), the rail measures to 1/10th AMP, so this is the only way they could really do it.

Because of this, you need to let MRTG know that the scale is 0.1

other than that... its very straight foward.

$Path is the Working directory, you need to create it before running it. $Community is the snmp community (usually public), $Host is the hostname/ip of the power rail, $name is the MRTG name of the instance. $Title is the friendly name. Easy?

Currently trending on twitter, #junipered means a few different things to a few different people. For anyone with marketing experience, it represents the blatent disregard for the cardinal rule of advertising. For Cisco fans, it's a reference to http://www.overpromisesunderdelivers.net , saying Juniper over promises and is a vendor of vaporware that is only hurting its customers. For Juniper fans, its a sign that Cisco is launching a childish advertising campaign as they're loosing market share to Juniper.

For me, it's sad. As a cisco fan, I'm a little worried that they're stooping this low, and certainly taken away from their image they I had of them. This is the first time I've seen them actually acknowledging the competition in any other way besides performance comparisons (and always retaliated against with TCO comparisons).

I'm sure everyone can see many sides to this, but what will be most interesting, is Junipers response, if any.

My heart sank. I feared for the worst. I had infact ejected and re-inserted the battery in close succession when it had frozen earlier that day.

I installed the HTC adb and fastboot drivers, android SDK and platform tools, booted the clockworkmod bootloader (yes, was already s-off and gingerbroken), and started throwing some adb commands at it from here - http://forum.xda-developers.com/showpost.php?p=16135893&postcount=27

adb shell cat /sys/devices/platform/msm_sdcc.2/mmc_host/mmc0/mmc0:0001/name

M4G2DE

... bugger, he thought.

adb shell  dmesg | grep mmc0

lots of i/o errors, but most importantly...  mmc0: Deferred resume failed

... bugger, bugger, he thought. the phone gods were angry with me.

Just as the xda-developer prophecy fortold, your mmc will stop working if its a M4G2DE and you don't treat the battery nicely.

My next thought was, restore the original boot and recovery and try and plead my case for a warranty... I doubted they'll be kind to me if they saw clockworkmod on boot.

so, I pulled apart the HTC telstra RUU and got the boot.img and recovery.img ready for a fastboot (more drivers required.. agh.) and was presented with

C:\android\tools>fastboot.exe flash boot ..\boot_signed.img
      sending 'boot' (2836 KB)... OKAY [  0.495s]
                writing 'boot'... FAILED (remote: not allowed)

... That's a bit rude, same thing for recovery.img.

As a last stich attempt, I booted back into fastboot, and ran the telstra RUU again. as i couldn't use adb to see the kmsg, I assumed it was going poorly... until... it booted!

failing to believe what I was seeing.... I ran the same command given to me to check the mmc... and..

SUCCESS! Potentially good news for anyone mid-heart-attack, your phone might not (but still could be) screwed.

I have since re gingerbroken, installed Cyanogen, and am back up and running with a working phone.

------

Update 20/9 - phone has been operational for about a week now, all is good.

To follow up a few questions - logs did indicate "failed to get card ready" , "deferred resume failed", several DMA errors, several (thousands of lines) of i/o errors. I guess something I've taken from all of this is that its possible that the current tests accepted on XDA to determine a hardware fault are not conclusive. I was ready to prepare my phone for a warranty (if I was lucky) repair, and installing the stock RUU fixed the issue. I have no doubt that there are people with a physically damaged emmc out there, but I was not one of them, and I think that means I'm not alone - so don't give up yet, try and flash the RUU from fastboot.

I was asked on XDA to prepare a filesystem and format it, and confirm there were no errors - there were not.
