We need to monitor a database table for response time of an action within our system. If the response time is above a threshold, we need to send an alert with details of the action: action_type, action_name, and others.
Is this possible with Zabbix?
I tried creating a Database monitor item with the following sql:
select action_type, action_name, window_title, response_time from db.table order by action_timestamp desc limit 1;
I was hoping that Zabbix would be able to store and display all the fields in the select, but it just gets the first value (for action_type) and not all the fields.
Is there a way to do it with Zabbix? It's pretty much a must for us so if we can't do it we'd have to go with a different monitoring tool.
EDIT: here's the notification syntax from an Action that is created hoping to use multiple values - from multiple items - in a notification sent following a trigger. My question here is, is this the correct syntax? Is my attempt at using multiple items in Item values: below going to work?
Trigger: {TRIGGER.NAME}
Trigger status: {TRIGGER.STATUS}
Trigger severity: {TRIGGER.SEVERITY}
Trigger URL: {TRIGGER.URL}
Item values:
1. Action name: {"Item ##5 Name"} ("Zabbix_server"}:{ITEM.KEY1}): {ITEM.VALUE1}
2. Window type: {"Item ##2 Name"} ("Zabbix_server"}:{ITEM.KEY2}): {ITEM.VALUE2}
Original event ID: {EVENT.ID}
If a query returns more than one column, only the first column is
read.
Reference: https://www.zabbix.com/documentation/2.4/manual/config/items/itemtypes/odbc_checks
=> You can't process more than one value per item out of the box, because Zabbix design. You can still create one item/query per field.
You can use some workarounds (zabbix UserParameter return 2 or more values), but you will hit another limitations.

Trying to setup Zabbix to show incomming login failures by syslog log files. I try to create an trigger which triggers when the last value occurs in the last 5 minutes of x amount of items.
The following expression is created:
Code:
count(/Syslog server/log[/var/log/failedlogin.log],5m,"like","last(/Syslog server/log[/var/log/failedlogin.log],#0)")>3
Also the following does not work:
Code:
count(/Syslog server/log[/var/log/failedlogin.log],5m,"like","{ITEM.LASTVALUE}")>3
I'm sure the count function works like it should be, when i fill in de variable manually the item does trigger.
But when i try to get a value out of an other items which is containing the data is seems to not work.
Could someone tell me if this is even possible? Thanks and greetings.
I'm trying to filter my users list by comparing two parameters
query="EmployeeData.EmployeeID=externalId"
EmployeeData.EmployeeID is a custom schema that is populated, with a cron job, with the same value as externalId.
Of course I let the cron do the field copy only if necessary, this is the reason I'm trying to filtering the users list.
In the way i wrote seems that the query trying to looking for a value "externalId" into the EmployeeData.EmployeeID ignoring that "externalId" is a even a field
any suggestion?
The way your code is written, the query sent to Google's servers is as you correctly guessed the following:
EmployeeData.EmployeeID=externalId where your actual externalId is not sent but rather the string "externalId".
To replace this string for the actual value of your variable, you can use what is called "string concatenation" 1. To do it, you just need to modify your code as shown below:
query="EmployeeData.EmployeeID=" + externalId;
This way, the query will be sent as you need to Google's servers.
I have a table tblItems with a list of inventory items. The table has many columns to describe these items, including columns for SupplierName, SupplierOrderNumber and PredictedArrivalDate.
If I order several new items from a supplier, I will record each item separately in the table with the same supplier name, order number and a predicted arrival date.
I would like to add a data macro, so that if I update the PredictedArrivalDate for one record, the value will be copied to the PredictedArrivalDate column of other records/items with the same SupplierName AND SupplierOrderNumber.
The closest I've got is:
SetLocalVar (MySupplierName, [SupplierName])
SetLocalVar (MySupplierOrderNumber , [SupplierOrderNumber ])
SetLocalVar (MyPredictedArrivalDate, [PredictedArrivalDate])
For Each Record in tblItems
Where Condition = [SupplierOrderNumber] Like [MySupplierOrderNumber] And [SupplierName] Like [MySupplierName] And [PredictedArrivalDate]<>[MyPredictedArrivalDate]
Alias OtherRecords
EditRecord
SetField ([OtherRecords].[PredictedArrivalDate], [MyPredictedArrivalDate])
End EditRecord
However, when I run this, only 5 records update, and the error log reports error -20341:
"A data macro resource limit was hit. This may be caused by a data
macro recursively calling itself. The Updated() function may be
used to detect which field in a record has been updated to help
prevent recursive calls."
How can I get this working?
I'm not one for using macro's to do anything, so I'd use VBA and recordsets/an action query to do the updating.
You can call a user-defined function inside a data macro by setting a local var equal to its result.
Access doesn't like data macros triggering themselves (which you are doing, you're using an on update macro and updating fields in the same table on a different record), because there is a risk of accidentally creating endless loops. Looks like you triggered a measure that's made to prevent this. I'd try to avoid that as much as possible.
Note: using user-defined functions inside data macros can cause problems when you're linking to the table from outside of Access (via ODBC for example).
This isn't a good solution (it's not a data macro), but it does work as a temporary fix.
I created an update query called "updatePredictedArrivalDate":
PARAMETERS
ItemID Long,
MyPredictedArrivalDate DateTime,
MySupplierName Text ( 255 ),
MySupplierOrderNumber Text ( 255 );
UPDATE tblItems
SET tblItems.PredictedArrivalDate = [MyPredictedArrivalDate]
WHERE (((tblItems.SupplierName) = [MySupplierName])
AND ((tblItems.SupplierOrderNumber) = [MySupplierOrderNumber])
AND ((tblItems.ID) <> [ItemID]));
On the PredictedArrivalDate form field .AfterUpdate event, I then added this macro:
IF [PredictedArrivalDate].[OldValue]<>[PredictedArrivalDate] Or [PredictedArrivalDate]<>""
OpenQuery (updatePredictedArrivalDate, Datasheet, Edit, [ID], [PredictedArrivalDate], [SupplierName], [SupplierOrderNumber])
I now have to remember to add this .AfterUpdate event to any other forms I create that amend that particular field.
If anyone has a better solution, please let me know.
I have recently started managing an Access DB used for reporting. Currently a single row has a 'status' that can be one of many options selected by a dropdown field. When reporting, each of these ~15 statuses rolls up to one of 5 'rollup statuses' which is currently translated via an Excel interface. I would like to add a column to the database table that automatically populates the correct 'rollup status' based on the selected 'status'. I do not know if this is a calculated field, a lookup, etc. as I have very minimal Access knowledge.
For example:
[Status]---->[Rollup Status]
To Be Scheduled----> Planning
TBD---->Planning
Scheduled---->Scheduled
DMM Pending---->Scheduled
EEP Created---->Scheduled
Cleanup Pending---->Complete
Complete---->Complete
If i understand your question correctly perhaps this would work...
In design mode: Add the new column to your table (which i will call 'total') where you want the 'rollup statuses' and call it something like 'rollup_status'
In SQL Query mode:
UPDATE total
SET rollup_status = '1'
WHERE [status] = '2';
I have an item of type float, but sometimes a string is received in case of error instead of a number. How can I make a trigger regexp to fire in this case?
I have no idea now to check for "wrong data type".
Actually this is by design and what I'm trying to do is this: if the data gathering fails, I send an error message in order to see it on zabbix end.
I tried with nodata(0), but this doesn't seem to work.
In you case zabbix will not store the "wrong" value for the item. And if you don't care what the string is then you can just setup a trigger for "nodata" for the period of your interval. Look in the triggers manual and search for the "nodata".
Edit: scratch that, didn't read the whole question ....
Edit2: if you are certain that this is not working by design and not because your trigger interval misses the data interval, then you can try to catch the unsupported status. There is an open request for the functionality, but you can setup a side script similar to this. Or you can wrap the monitored item on the node into a UserParameter script that reads the value and prints -1 or something if it is not a number. Then proceed with a normal numeric trigger.
