JRExecAction() function behavior in Netcool Impact

Just a short post today to set the record straight on the use of the JRExecAction() function in Netcool Impact policies.

The product documentation states that the JRExecAction() function returns nothing, but sets the variables ExecError and ExecOutput corresponding to stderr and stdout from the script/command that you run. However, the function itself returns the data written to stdout in addition to setting ExecOutput and/or ExecError. So if you try the following, you'll see that the same output is logged twice:


results = JRExecAction("/bin/ls", "/", false, 1000);
log(0,"Frank results = " + results);
log(0,"ExecOutput results = " + ExecOutput); 


Incidentally, the first use above is really the more common use in practice. You will find very few implementations where the ExecOutput variable is referenced.

Customizing the ServiceNow Netcool Connector

UPDATE 5/1/2020

You can update this script through the ServiceNow GUI. The navigator item to select is "Script Files" under "MID Server". And the name of the script is NetcoolConnector. Edit in the GUI and it gets updated on all of your MID servers.

Background

The ServiceNow Netcool Connector (introduced at some point before the New York release) allows you to pull events from a Netcool ObjectServer into ServiceNow. The connector is a process that runs on a MID Server. Within the ServiceNow interface, there are only a few configuration options (userid/password, JDBC URL, how often to run, etc.). However, there are no filters to configure. That's because the connector is a straightforward Groovy script that you can edit as needed on the MID Server.

Details

The Netcool Connector script is found on the MID Server in the file .../agent/scripts/Groovy/NetcoolConnector.groovy. Some of the interesting parts of the script are the actual query that's run:

query = "select top 3000 Identifier,Node,NodeAlias,AlertKey, Manager,Agent,AlertGroup,Severity,Type,Summary,Acknowledged,LastOccurrence,StateChange,SuppressEscl from alerts.status where StateChange > " + lastTimeSignature + " and Manager not like '^.*Watch\$' order by StateChange asc";


That is exactly the query that's run, and you can edit it to include custom fields, for example. To complete the customization, you also need to update the createEvent() function to actually include those custom fields in the event that's created in ServiceNow. In there you can also do any hard-coded transforms that are required or anything else.

Short script to generate continuous random events to Netcool OMNIbus

So you need to generate some events to OMNIbus? It's really easy with the nco_postmsg shell script that's installed on your ObjectServer host:

while (true); do nco_postmsg -user root -password n3tc00l "Identifier='my_identifier_${RANDOM}'" "Node='mynode${RANDOM}'" "Severity=5" "Manager='nco_postmsg'" "Summary='An event occurred again'" "ImpactFlag=1" "AlertGroup='FRANK_${RANDOM}'"; sleep 10; echo sending another event; done

Update the user and password parameters, and you can add any fields you need. It simply generates an event every 10 seconds.

Some of our current projects

We work with a pretty wide array of products, so I wanted to highlight some of the projects we're working on right now

ServiceNow Architecture and Implementation

We're working with a communications company to implement their procurement, installation and change processes within ServiceNow, with asset feeds from multiple external systems.

ServiceNow Incident Response integration with QRadar

We're helping our client customize both products and the integration between them to best leverage their existing investment and people.

IBM Control Desk for Field Service Management

We're helping a different communications customer with their field service management through workflows and custom user interfaces defined in IBM Control Desk.

Netcool Operations Insight Implementation

We're actually working on several of these at the moment. The most work on these goes into identifying the different event sources, what (if any) automated actions need to be performed and who needs to be notified.

BigFix Steady State

A medical client of ours has been leveraging our BigFix Managed Services for several years to ensure that all IT equipment is both known and is running software at the appropriate patch level.

ICD and BigFix Implementation with Airgap

We're working with a defense contractor to ensure that their Asset Management and Change Management processes continue to work smoothly leveraging ICD and BigFix

More IBM Netcool Agile Service Manager Videos

I think some wires got crossed in YouTube recently as IBM Service Management moved over to the IBM Cloud channel, and it appears that their most recent videos are hidden from any searches. However, thanks to Matt Duggan from IBM who shared the direct links on LinkedIn, I've added them all to my own IBM Agile Service Manager playlist, which can be found here:

IBM Netcool Agile Service Manager - What is swagger?

Introduction

The ASM documentation references "swagger" and "swagger URLs" for several different services. The purpose of this post is to describe what this actually means.

What is swagger?

Here's a statement from swagger.io:

The goal of Swagger™ is to define a standard, language-agnostic interface to RESTAPIs which allows both humans and computers to discover and understand the capabilities of the service without access to source code, documentation, or through network traffic inspection.

So the goal of this article is to show what that statement actually means to you in the context of Agile Service Manager.

Swagger URLs for ASM

There are 7 different services that are accessible via a browser. My ASM host is named "asm", and here are the URLs I have for the services:

File Observer Swagger UI
http://asm:9098/1.0/topology/observer/swagger/#/
        
topology-service Swagger UI
http://asm:8080/1.0/topology/swagger#/ 
        
search service Swagger UI
http://asm:7080/1.0/search/swagger  
        
ITNM observer Swagger UI
http://asm:9080/1.0/topology/observer/swagger   
        
OpenStack observer Swagger UI
http://asm:9082/1.0/topology/observer/swagger   
        
Event observer Swagger UI
http://asm:9084/1.0/topology/observer/swagger 
        
Docker observer Swagger UI
http://asm:9086/1.0/topology/observer/swagger 

Topology Service

The Topology Service is the one that will be the one you normally want to visit to view (and even change) data about the resources in the ASM database. Here's what you'll see when you access the URL:

You can click on each section to see the operations associated with each. The section I like is Resources. Here are the operations found there:


From here, you can click on one of the operations, such as the first one: GET /resources. Here's just the first part of what's displayed there:



Notice that it gives you documentation about the operation and lots of other information. Specifically, it provides you with the ability to fill in values for all of the parameters that the operation accepts AND allows you to execute the operation! It also provides you with the 'curl' command that you can run from the command line to execute the exact same operation, with the exact same parameters.

The way to execute the operation is to click the "Try it out!" button at the bottom of the operation documentation.


And there you go! Some data. In this case, what's returned is the ID of the node in the topology that matches the criteria I specified. I can then take this ID and use it as input to other operations in this same group or in other groups.

Try it out and have fun

The above is just an short entry point into ASM's swagger UIs. Play around with them and you'll see that you can do some interesting stuff.

Agile Service Manager UI Introduction

Here's a short video introduction covering the basic features of IBM's Netcool Agile Service Manager.





IBM Netcool Agile Service Manager Thoughts

I recently installed IBM's Netcool Agile Service Manager and wanted to give my initial thoughts on it.

What is Agile Service Manager?


Basically, it's a real-time topology viewer for multiple technologies. Specifically, it can currently render topology data for ITNM, OpenStack and Docker, all in one place. Additionally, it maps events to the topology so you can see any events that are affecting a resource in the context of its topology. So, for example, if you receive a CRITICAL event for a particular Docker container, you will see the node representing that container turn red. Pretty neat. Here's an example of a 1-hop topology of my ASM server's docker infrastructure (you always have to start at some resource to view a topology):



What's so great about it?

Combined Topology View

First, this topology view is wonderful for Operations and Development because it shows a topology view of your combined Network, Docker and Openstack environments, so everyone can see where applications are running and the dependencies among the pieces.

ElasticSearch

Second, it's got ElasticSearch under the covers, so updates and searches are amazingly fast, and the topology view is built extremely quickly.

Custom Topology Information

Third, you can add your own topology information to make it even more useful!

Here's a screenshot where I've manually modified the topology using a combination of the File Observer and direct access to the Topology Service REST API (from the Swagger URL):



Notice also that Time Entry is in a Critical state. That's due to an event that I generated.

History

Fourth, it maintains history about the topology. That means that you can view the difference in topology between 2 hours (or two days) ago and right now.

Is ASM a complete replacement for TBSM and/or TADDM?


No, ASM is not a complete replacement for TBSM or TADDM, but you can definitely think of it as "TBSM Lite". TBSM still has some very unique features, such as status propagation, service rules, and custom KPIs that can be defined on a per-business-service basis.

And TADDM's unique capability is the hard work of actually discovering very detailed data and relationships in your environment.

However, because the search and visualization pieces of ASM are so fast and efficient, I can definitely see ASM being used as at least part of the visualization portion of  TADDM. What would be required to allow this is a TADDM Observer to be written.

Additionally, I think the ASM database and topology will in the future be leveraged by TBSM, though this will take a little work.

Parting thoughts

ASM is a truly useful product, with some great capabilities. It's also incredibly easy to install if you've already got Netcool Operations Insight (or at least DASH) installed - I was able to get it installed in just a few hours. I'm certain IBM will be adding features and add-ons to provide even more functionality in the coming months.

How to Convert Remedy Time to UTC TimeStamp

This question came up on the INUG-USERS mailing list the other day, and our own IV Blankenship was the person who came to the rescue:

Question:
Using Impact WebService we capture the Ticket Close time from Remedy.

I observer Remedy sends the datetime in the below format. How to convert
the below format to NetCool UTC datetime format and display in NetCool
Dashboard.

*2016-02-23T20:45:09-08:00 -> with timezone embedded*



Answer:
The Impact ParseDate function is a wrapper for the Java SimpleDateFormat
class (
http://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html)

The problem with your date string is the timezone. SDF and ParseDate by
extension expect it to be (+-)NNNN not (+/-)NN:NN.
Also, you have to escape the T using single quotes.


You did not say if you were using IPL or Javascript, but here is some IPL
that will work and verify that your data is in the expected format.

d="2016-02-23T20:45:09-08:00";
if(d like '(\d\d\d\d\-\d\d\-\d\dT\d\d:\d\d:\d\d)([\+\-]\d\d):(\d\d)$') {
  parts=RExtractAll(d,
'(\d\d\d\d\-\d\d\-\d\dT\d\d:\d\d:\d\d)([\+\-]\d\d):(\d\d)$');
  tempDateString=parts[0]+parts[1]+parts[2];
  Log(0,tempDateString);
  f="yyyy-MM-dd'T'HH:mm:ssZ";
  pd=ParseDate(tempDateString, f, null);
  Log(pd);
}
else {
  Log(0,"Unsupported date format!");
}

Launchpad - Unable to find supported browser

Recently while trying to install Netcool Omnibus 7.4 on CentOS 6.4, I ran into this problem:

I launched the Omnibus launchpad.sh script only to be told that the browser I was using was not supported:

"An error occurred while starting the launchpad. This error typically occurs when the launchpad is unable to find a supported browser. Check your product's documentation for a list of supported browsers."


But, the HTML file (noBrowser.html) was actually displayed by Firefox.  It turns out that the version of Launchpad only supports older versions of Firefox, namely ESR10.

There is a very simple fix to this issue:

1) Download an ESR10 version of Firefox, for example:

# cd /tmp
# wget https://ftp.mozilla.org/pub/mozilla.org/firefox/releases/10.0.2/linux-x86_64/en-US/firefox-10.0.2.tar.bz2

2) Extract it:

# cd /tmp
# tar -jxf firefox-10.0.2.tar.bz2

3) Tell Launchpad to use it

# export BROWSER=/tmp/firefox/firefox

4) Relaunch launchpad.sh

# /tmp/omni-install/launchpad.sh

and now it works:
