Printer Errors Test

This test indicates whether a particular measure generates a Critical warning or a Non-critical warning. A Critical warning is indicative of a problem so severe, that the printer is rendered unavailable until the warning is attended to. A Non-critical warning is one wherein the printer will continue to remain available despite the warning.

Target of the test : A Printer

Agent deploying the test : An external agent

Outputs of the test : One set of results for the printer being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.


The IP address of the host for which this test is to be configured.


The port at which the monitored target exposes its SNMP MIB; The default value is 161.


By default, the eG agent supports SNMP version 1. Accordingly, the default selection in the SNMPversion list is v1. However, if a different SNMP framework is in use in your environment, say SNMP v2 or v3, then select the corresponding option from this list.


The SNMP community name that the test uses to communicate with the firewall. This parameter is specific to SNMP v1 and v2 only. Therefore, if the SNMPVersion chosen is v3, then this parameter will not appear.


This parameter appears only when v3 is selected as the SNMPVersion. SNMP version 3 (SNMPv3) is an extensible SNMP Framework which supplements the SNMPv2 Framework, by additionally supporting message security, access control, and remote SNMP configuration capabilities. To extract performance statistics from the MIB using the highly secure SNMP v3 protocol, the eG agent has to be configured with the required access privileges – in other words, the eG agent should connect to the MIB using the credentials of a user with access permissions to be MIB. Therefore, specify the name of such a user against this parameter. 


This parameter appears only when v3 is selected as the SNMPVersion. An SNMP context is a collection of management information accessible by an SNMP entity. An item of management information may exist in more than one context and an SNMP entity potentially has access to many contexts. A context is identified by the SNMPEngineID value of the entity hosting the management information (also called a contextEngineID) and a context name that identifies the specific context (also called a contextName). If the Username provided is associated with a context name, then the eG agent will be able to poll the MIB and collect metrics only if it is configured with the context name as well. In such cases therefore, specify the context name of the Username in the Context text box.  By default, this parameter is set to none.


Specify the password that corresponds to the above-mentioned UserName. This parameter once again appears only if the SNMPVersion selected is v3.

Confirm Password

Confirm the AuthPass by retyping it here.


This parameter too appears only if v3 is selected as the SNMPVersion. From the AuthType list box, choose the authentication algorithm using which SNMP v3 converts the specified username and password into a 32-bit format to ensure security of SNMP transactions. You can choose between the following options:

  • MD5 – Message Digest Algorithm
  • SHA – Secure Hash Algorithm


This flag appears only when v3 is selected as the SNMPVersion. By default, the eG agent does not encrypt SNMP requests. Accordingly, the this flag is set to No by default. To ensure that SNMP requests sent by the eG agent are encrypted, select the Yes option. 


If this EncryptFlag is set to Yes, then you will have to mention the encryption type by selecting an option from the EncryptType list. SNMP v3 supports the following encryption types:

  • DES – Data Encryption Standard
  • AES – Advanced Encryption Standard


Specify the encryption password here.

Confirm Password

Confirm the encryption password by retyping it here.


Specify the duration (in seconds) within which the SNMP query executed by this test should time out in this text box. The default is 10 seconds.

Data Over TCP

By default, in an IT environment, all data transmission occurs over UDP. Some environments however, may be specifically configured to offload a fraction of the data traffic – for instance, certain types of data traffic or traffic pertaining to specific components – to other protocols like TCP, so as to prevent UDP overloads. In such environments, you can instruct the eG agent to conduct the SNMP data traffic related to the monitored target over TCP (and not UDP). For this, set this flag to Yes. By default, this flag is set to No.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Is paper available

(Critical warning)

Indicates the availability of papers in all trays


A value of 0 indicates that there are no papers  in any of the trays.  If the value is 1, it means that papers are available in at least one tray.

Toner capacity

(Non-critical warning)

Indicates the status of the toner with respect to its capacity


A value of  0 indicates that the toner capacity is low. However, if the value is 1 it indicates that there is adequate toner in the printer.

Is toner available

(Critical warning)

Indicates whether a toner is available for printing or not


A value of 0 is indicative of either of the following scenarios:

  • The toner cartridge is not physically present in the printer
  • The printer is out of toner

A value of 1, on the other hand, confirms the physical presence of the toner cartridge and its availability for printing.

Paper flow status

(Critical warning)

Indicates whether the flow of paper into and out of the printer is smooth


A value of 0 indicates that there is a paper jam and a value of 1 indicates that  the paper flow is smooth

Is online

(Critical warning)

Indicates whether the printer is on line or off line.


A value of 0 indicates that the printer is off line. If the value is 1, it denotes that the printer is on line

Is door closed

(Critical warning)

Indicates the overall status of the doors/covers present in the printer


This measure is available only for printers with doors / covers.


While a value of 0 indicates that the door is open, 1 indicates that it is closed.
