MySet2 Flashcards by Ed B

You receive a number of alerts on high traffic utilization from several interfaces. When you view the Orion Web Console, you find that traffic utilization has returned within normal ranges. Traffic utilization spikes every now and then and you don’t usually consider it a problem. How should you modify the alert definitions so that it fires only when high utilization is sustained for 10 minutes or more?

Configure the alert to trigger only when traffic utilization is sustained for 10 minutes

You are required to report on hourly average response time of the last 60 days. How should you configure your data collection and summarization parameters to meet these requirements without unnecessarily using database size?

Summarize detailed data into hourly data after 30 days, summarize hourly data into daily data after 60 days

You are working on a critical device and would like to have its own set of threshold for CPU Load and Memory usage apart from the Orion general threshold. The Orion general is set to 80% for CPU Load and 80% for Memory usage before your devices are set to Critical but we do like to have a lower value on your critical device. How can we achieve this?

We can set it up on the node level and select override Orion general threshold, select CPU Load and Memory and enter the desired values.

How do we ensure that only the SolarWinds Platform server can initiate communication to the SolarWinds Platform agent?

a. The agent retains a copy of the public Orion certificate obtained during provisioning. Passive mode uses this to authenticate the server.
b. The Server and Agent perform three-way handshake
c. The Agent uses token-ring to authenticate to the Orion Server

a. The agent retains a copy of the public Orion certificate obtained during provisioning. Passive mode uses this to authenticate the server.

Under normal operating conditions, SolarWinds Platform agent monitoring consumes how many percent in terms of the resources than what would be consumed by monitoring the same node agentless.

less than 1% more resources than what would be consumed by monitoring the same node agentlessly.

Reference: https://documentation.solarwinds.com/en/success_center/orionplatform/content/core-agent-requirements-sw476.htm

Which of the following Situations is Agent most beneficial?

Polling hosts and applications behind firewall NAT or proxies.
Secure, encrypted polling over a single port.
Support for low bandwidth, high latency connections.
Polling nodes across domains where no domain trusts have been established.

How much memory does an Agent typically consume?

10 - 100 MB, depending on the number and types of jobs.

You are creating an alert for a Universal Device Poller (UnDP). Which of the following trigger condition helps you target the custom poller you want?

A trigger condition where the custom poller Unique Name is equal to the name of your UnDP

Configure the alert to trigger only when traffic utilization is sustained for 10 minutes

The Web Console has multiple _____(s) with multiple _____(s) which display information about your ______(s).

-Views, Widgets, Entities

While attempting to add a device to Orion for monitoring, you find that Orion can communicate with the device for latency measurements, but is not able to pull data such as CPU load or interface traffic. What should you verify first?

that you have the correct SNMP community string for the device

While monitoring your network with Orion NPM, you notice that several of the devices in your remote offices periodically go into a “warning” state, but then quickly go back into an “up” state. While the devices are in “warning” state, the users at those sites report normal operations. What is the most likely cause of this occurrence?

During network congestion, ICMP Packets are being dropped

Which two variables are used in the calculation of Percent Utilization?

configured bandwidth
bps

You notice that several routers are showing an increase in CPU and memory utilization that is starting to concern you. What will likely happen if this trend continues?

Latency through the routers will increase

Over the course of 24 hours, a node was sent 200 ping requests in an effort to monitor its availability.Of those 200 ping requests there were:100 responses of less than 10ms50 responses of greater than 20ms50 requests with no responsesWhat was the availability of that node during this period of time?

75%

Orion is displaying a device as "down" and is unable to communicate with the device via ICMP. However, you are able to ping that device from the command-line on the Orion server. Orion is displaying other devices as being "up".What is a possible cause of this issue?

ICMP messages with content in the payload portion of the packets are being blocked

While isolating a bandwidth issue in NPM, you discover that the percent utilization for an interface is over 100%.What is a possible cause?

It is configured with the wrong interface speed

You want to get an alert when disk space used on a server exceeds 90%, but you will not consider the problem fixed until the space used drops below 60%.You want to get an email when the problem occurs, but you also want an email when the problem is fixed. While the problem remains unfixed, you want the alert to stay active in the Orion NPM Web Console. If you create an alert with a trigger condition such as "Volume Space Used is greater than 90%," you will get an email when the initial problem occurs.What is the next step that is required to accomplish this goal?

add a Reset Condition like "Volume Space Used is less than 60%"

Which limitation does the Orion NPM Advanced Alert Engine place on trigger and reset actions?

unlimited trigger actions and unlimited reset actions

You want to monitor a specific device attribute that Orion NPM does not support by default. Which type of content should you download from the Thwack Content Exchange?

UnDP

An Orion NPM user wants to be able to make changes to the resources as they view them on the Orion Web Console. What must be done to the user's account?

Allow View Customization must be enabled

Your network has a few critical devices on the other side of a WAN link from your Orion server. If the router (name = "target") connecting Orion to the remote site goes down, you do not want alerts about those devices.How should you configure Orion NPM Alert Suppression within the Advance Alert Engine to achieve your goal?

suppress alert when all of the following apply: Node Name is equal to "target" | Node Status is equal to "Down"

When you look at utilization graphs for a given interface, they show greater than 100% utilization. Which interface configuration change will correct this issue?

Increase custom bandwidth

You have created a new account in the Orion NPM website that requires that only nodes that contain the string 'Core' in their hostname should be seen.Which two steps should you take in Orion NPM to accomplish this?

set the pattern to *Core* add an Account Limitation based on Node Name Pattern

You need to write a report that shows network response time on an hourly basis for the past 30 days. When you try to set the summarization setting in the report to hourly, you get a reporting error. What is a possible cause of this issue?

Hourly data are being summarized into weekly data after 15 days

As your Orion NPM deployment grows, you need to add pollers to the system, but due to budgetary constraints, you are unable to do so. What should you do in the short term to allow you to add a few more elements?

adjust polling intervals

What would cause an NOC user's account to stay logged in indefinitely?

using Account Manager to disable timeout on the NOC user
