Device Tables are not ingesting tables for an orgs workspace
Device Tables are not ingesting tables for an orgs workspace. I can confirm that all devices are enrolled and onboarded to MDE (Microsoft defender for endpoint) I had placed an EICAR file on one of the machine which bought an alert through to sentinel,however this did not invoke any of the device related tables . Workspace i am targeting Workspace from another org with tables enabled and ingesting data Microsoft Defender XDR connector shows as connected however the tables do not seem to be ingesting data; I run the following; DeviceEvents | where TimeGenerated > ago(15m) | top 20 by TimeGenerated DeviceProcessEvents | where TimeGenerated > ago(15m) | top 20 by TimeGenerated I receive no results; No results found from the specified time range Try selecting another time range Please assist As I cannot think where this is failing
Sentinel Data Connector: Google Workspace (G Suite) (using Azure Functions)
I'm encountering a problem when attempting to run the GWorkspace_Report workbook in Azure Sentinel. The query is throwing this error related to the union operator: 'union' operator: Failed to resolve table expression named 'GWorkspace_ReportsAPI_gcp_CL' I've double-checked, and the GoogleWorkspaceReports connector is installed and updated to version 3.0.2. Has anyone seen this or know what might be causing the table GWorkspace_ReportsAPI_gcp_CL to be unresolved? Thanks!need to create monitoring queries to track the health status of data connectors
I'm working with Microsoft Sentinel and need to create monitoring queries to track the health status of data connectors. Specifically, I want to: Identify unhealthy or disconnected data connectors, Determine when a data connector last lost connection Get historical connection status information What I'm looking for: A KQL query that can be run in the Sentinel workspace to check connector status OR a PowerShell script/command that can retrieve this information Ideally, something that can be automated for regular monitoring Looking at the SentinelHealth table, but unsure about the exact schema,connector, etc Checking if there are specific tables that track connector status changes Using Azure Resource Graph or management APIs Ive Tried multiple approaches (KQL, PowerShell, Resource Graph) however I somehow cannot get the information I'm looking to obtain. Please assist with this, for example i see this microsoft docs page, https://learn.microsoft.com/en-us/azure/sentinel/monitor-data-connector-health#supported-data-connectors however I would like my query to state data such as - Last ingestion of tables? How much data has been ingested by specific tables and connectors? What connectors are currently connected? The health of my connectors? Please help
Microsoft 365 defender alerts not capturing fields (entities) in azure sentinel
We got an alert from 365 defenders to azure sentinel ( A potentially malicious URL click was detected). To investigate this alert we have to check in the 365 defender portal. We noticed that entities are not capturing (user, host, IP). How can we resolve this issue? Note: This is not a custom rule.
Microsoft Sentinel Query History not updating
Hello, Apologies if this isn't the correct place for this but I know I will likely retire before I get any traction with Microsoft support. Has anyone experienced issues with their Sentinel Query History not updating with the latest queries? I run a lot of queries each day and any time I open a new browser window and go to the logs tab, the latest query it shows in my history is 7/29/2025. If I run any new queries in that browser tab, they show in my query history but the moment I open a new browser tab and access sentinel logs, they are gone and it shows the latest query as 7/29/2025. My colleague has the exact same issue except their latest query date is 8/7/2025... Yes I do have the "Save query history" setting set to On. I have toggled it of and back on just to see if it would do anything but no luck. Does anyone know what could be causing this?
Standard Ontology and SIEM Field Mapping
Hello Community, We are working on a Microsoft Sentinel → Google Chronicle integration and need to automate the SIEM Field Mapping process between the two platforms Sentinel and google chronicle Schema Differences – Sentinel and Chronicle use different naming conventions and field hierarchies. Analytics Portability – Without mapping, a Chronicle rule expecting principal user email won’t understand Sentinel’s User Principal Name. Questions: Is there an API, PowerShell cmdlet, or Logic App method Sentinel’s field mapping with google chronicle fields.? is there any possibility via Automation.?
How to exclude IPs & accounts from Analytic Rule, with Watchlist?
We are trying to filter out some false positives from a Analytic rule called "Service accounts performing RemotePS". Using automation rules still gives a lot of false mail notifications we don't want so we would like to try using a watchlist with the serviceaccounts and IP combination we want to exclude. Anyone knows where and what syntax we would need to exlude the items on the specific Watchlist? Query: let InteractiveTypes = pack_array( // Declare Interactive logon type names 'Interactive', 'CachedInteractive', 'Unlock', 'RemoteInteractive', 'CachedRemoteInteractive', 'CachedUnlock' ); let WhitelistedCmdlets = pack_array( // List of whitelisted commands that don't provide a lot of value 'prompt', 'Out-Default', 'out-lineoutput', 'format-default', 'Set-StrictMode', 'TabExpansion2' ); let WhitelistedAccounts = pack_array('FakeWhitelistedAccount'); // List of accounts that are known to perform this activity in the environment and can be ignored DeviceLogonEvents // Get all logon events... | where AccountName !in~ (WhitelistedAccounts) // ...where it is not a whitelisted account... | where ActionType == "LogonSuccess" // ...and the logon was successful... | where AccountName !contains "$" // ...and not a machine logon. | where AccountName !has "winrm va_" // WinRM will have pseudo account names that match this if there is an explicit permission for an admin to run the cmdlet, so assume it is good. | extend IsInteractive=(LogonType in (InteractiveTypes)) // Determine if the logon is interactive (True=1,False=0)... | summarize HasInteractiveLogon=max(IsInteractive) // ...then bucket and get the maximum interactive value (0 or 1)... by AccountName // ... by the AccountNames | where HasInteractiveLogon == 0 // ...and filter out all accounts that had an interactive logon. // At this point, we have a list of accounts that we believe to be service accounts // Now we need to find RemotePS sessions that were spawned by those accounts // Note that we look at all powershell cmdlets executed to form a 29-day baseline to evaluate the data on today | join kind=rightsemi ( // Start by dropping the account name and only tracking the... DeviceEvents // ... | where ActionType == 'PowerShellCommand' // ...PowerShell commands seen... | where InitiatingProcessFileName =~ 'wsmprovhost.exe' // ...whose parent was wsmprovhost.exe (RemotePS Server)... | extend AccountName = InitiatingProcessAccountName // ...and add an AccountName field so the join is easier ) on AccountName // At this point, we have all of the commands that were ran by service accounts | extend Command = tostring(extractjson('$.Command', tostring(AdditionalFields))) // Extract the actual PowerShell command that was executed | where Command !in (WhitelistedCmdlets) // Remove any values that match the whitelisted cmdlets | summarize (Timestamp, ReportId)=arg_max(TimeGenerated, ReportId), // Then group all of the cmdlets and calculate the min/max times of execution... make_set(Command, 100000), count(), min(TimeGenerated) by // ...as well as creating a list of cmdlets ran and the count.. AccountName, AccountDomain, DeviceName, DeviceId // ...and have the commonality be the account, DeviceName and DeviceId // At this point, we have machine-account pairs along with the list of commands run as well as the first/last time the commands were ran | order by AccountName asc // Order the final list by AccountName just to make it easier to go through | extend HostName = iff(DeviceName has '.', substring(DeviceName, 0, indexof(DeviceName, '.')), DeviceName) | extend DnsDomain = iff(DeviceName has '.', substring(DeviceName, indexof(DeviceName, '.') + 1), "")KQL: setting query time leads to problem in watchlist column projecting
Hello to the community! I have stumbled upon a very strange issue when using watchlists. I have a watchlist with 2 columns (userPrincipalName,allowedActivity) that I am then using to whitelist activities. Watchlist is imported using: let WhitelistedUsers = _GetWatchlist("testQuery") | project userPrincipalName, allowedActivity; Then I wanted to set it to a specific time frame to test it on given data set: set query_now = datetime("1/14/2022, 1:45:46.556 PM"); Problem is that when setting my query for a specific time, I get the following error from the watchlist: 'project' operator: Failed to resolve scalar expression named 'userPrincipalName'. Commenting the set query_now solves the project problem (not my problem though). I tried to set the time before and after watchlist import but that does not solve the issue. I could not find any posts around the topic (quite a specific one), so anyone observed similar behaviors or has a possible explanation? I can probably work around the set query_now with other functions but I gotten used to it, and find this behavior extremely strange
Incident Missing Entities
Good morning! I would like to have some clarification on how entities work. Yesterday I found out that if I have 2 entities of the same type (In this particular case, two entities of the type Account), with the same identifier (originally, both share the identifier 'Name'), Sentinel appears to throw away one of them, or both in some instances, and when the alert generates an incident, the entities defined won't appear. I have switched out the identifier on both account types to something different, but until an incident gets triggered, I can't confirm if this will fix the original issue. So my questions are An analytic rule can or can't have two entities of the same type defined? If yes, that means that they need to have different identifiers. Is this a correct asumption? Some identifiers expect a certain type of value to be assigned, that means that eventually, I can ran out of identifiers for my entities or face the added complexity of dealing with types when returning values from my KQL query What could happen if I map an identifier to something that matches the type but not what that identifier represents? in this case, for Account, we have the identifier ObjectGuid. If I assign a value type string to it, that is not a guid, wouldn't that mess up something else in the background? Example, incident grouping If I move instead to use Sentinel Entities, which appear to be the 'general' option, I could only use one, since I only have 'entity' as available identifier, looping back to the problem of can have only one type of identifier for identity type. Thanks in advance
