Mulesoft / TP Training
Day 1
API Fundamentals
-
-
TP architecrture
-
backlog item: there is an internal TP (INT) set of reverse proxies and gateways used for staff facing services (mostly CMB). Need to identify runbooks, dashboards for internal platform.
backlog item: have cross data center connectivity in HK but not in UK/US - why? According to Ash there is a reason, we need to follow that up.
-
-
Gateway Proxy Processing: HTTP listener > API Kit > Policy Execution > HTTP > PCF. You can also apply policies on the way out
backlog item: we have lots of DSDs for manual configuration of security policies within PCE - why is it manual?
-
-
Day 2
-
PCE
backlog: useful to check how many APIs running on a gateway cluster - could be done via an API call to PCE and then displayed on a dashboard.
-
API deployment flow: 1 - deployment notification, 2 - successful deploy, 3 - gatekeeper blocks, 4 - policies applied, 5 - gatekeeper unblocked
Gateways

backlog: we continue to see rProxy <>gateway disconnecting errors. Known issue where a short connectivity issue triggers an rproxy disconnection for 60 seconds. Alert: DPSRE DTP-RP_DISCONNECTED_GW alert was triggered
Day 3
Monitoring
rProxy
Common Errors: 500, 502 - bad gateway, 503 - service unavailable, 403, 429
backlog: we need to check if the apache extension is fully applied across the TP estate (internal/external)
-
gateway
-
backlog: our entry point (DNS) management is only one rbwm-api-[region]. However there are some consumers who have defined thier own GSS entry points which we do not manage.
backlog: team has noticed that appd infra metrics do not seem accurate when compared to metrics gathered from the box. e.g. cpu load
-
-
backlog: Review the AppD/Splunk Alerts being sent to DI that should be shared with DPSR as an interested party.
